Inpossible to access website with Vodafone and chrome/opera - google-chrome

we have a connection error based on a combination of vodafone mobile germany network combined with chrome/opera browser, but other combination with vodafone mobile network with firefox is working.
If you want to access to page https://waschmal.de, then you will receive an error message, that host cannot be found. You can find a screenshot which was made, after I switched to mobile teathering.
If you access the page with D1 or O2 and chrome, than everything is working fine.
Vodafone has no idea how to solve that.
I also shut down firewall and retried to access, but also no connections are possible by this combination.
It would be so awesome if someone can help out!

the problem was based on Tomcat 8. Upgrading to 9 solved this problem

Strange Simplified chinese message shows on EVERY browser on my Linux mint 18.02

I don't know when and how the screen start to show on my EVERY browsers(firefox, chrome, chromnium..). When I input any words in the address line of browsers, the result will lead to the scree.
I had unistall and reboot and reinstall the firefox and chrome some many times recently, this message still exits....
I wonder how and why it shows on my EVERY browser of Linux mint 18.02. And please tell me how to remove or back to the original status. Thank you.
Because I use my T410i which is installed Linux mint 18.02 at home always, and that means I always connect with our community's wifi. Today, I took my T410i to my working space and using wifi there. Everything is fine!
It seems that the wifi route or server leads to the issue. However, I haven't talk with the administrator of our community's internet service. For now, we only can be sure that the issue is not triggered by Fcitx, Chrome, or Firefox.
If we find the final result, we will update the answer here:)

Loading resources via URL is slow in Chrome - ONLY via https, ONLY from one specific website

I have this 1 Mb file for testing purposes (though the issue applies to any file hosted at lptoronto.com): https://lptoronto.com/sandbox/test.png
It always loads instantly in Internet Explorer (both via http and https).
In Google Chrome (currently Version 63.0.3239.132 (Official Build) (64-bit) on Windows 10) the situation is as follows.
When fetched via http, this file loads instantly without an issue.
When fetched via https, the same file takes about 40 (!) seconds to load (with very rare and irregular exceptions, when it also loads fast via https on occasion).
Chrome network monitor shows that all that 40 seconds the image is being slowly but steadily downloaded at low speed, i.e. there is nothing like waiting for server response etc.
Here's the screencast showing IE and Chrome side-by-side loading the same image:

From time to time the issue disappears for a few minutes or an hour, but then re-appears again, without me doing anything on my side.
Same behavior is observed on at least one other computer - the one of my colleague (different ISP, different location).
Needless to say that I'm testing in a clean environment - cache cleared, extensions, firewall, antivirus disabled, connection verified and measured etc.
No Chrome issue whatsoever with any other website, be it http or https.
Hosting provider is yet unable to troubleshoot on their end, but they're still trying to help (it takes some time). They tried disabling mod_deflate, re-installing SSL, disabling caching rules, but to no avail.
The same issue was once observed about 2 months ago. That time I asked the hosting provider to disable SSL completely just to be able to work on my website content. When they re-enabled SSL in less than a day, the issue has gone; but now it re-appeared again, and there is no clue as to what is going on.
The bottomline:
issue appears only in Chrome, only with certain site, only with https
changing only the browser solves the issue
changing only the protocol (https to http) solves the issue
I honestly tried to google out anything similar, but failed to.
I would appreciate if you try the link above in the incognito Chrome window and report the load/refresh time, and of course any ideas are more than welcome.

CreatePushNotificationChannelForApplicationAsync throws 0x880403E9 error

I am making a Windows Phone 8.1(winrt flavor) application and stuck in problem about PushNotification.
await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();
This function returns PushNotificationChannel and it usually works well. But in some our devices, this function throws 0x880403E9 error.
MSDN says,
0x880403E9 The notification platform is in the process of reconnecting back to the WNS cloud due to a earlier network connectivity change. Apps should retry the channel request later using an exponential back-off strategy.
I think retrying the request can never solve this problem. The function always throws the exception. During a month. We even implemented exponential retrying strategy.
The worse fact is, the our broken devices worked well with the function before. But once it has been broken(?) by mysterious reason, it is never fixed itself. -First time we've got this problem, we did factory-reset the device and the problem fixed. But in other devices, reset was not a solution.
Somebody says updating lastest version might solve this problem, but it is not. Even in Windows Phone 8.1 Update 1(8.10.14157.200), the problem still occurs.
Is there anyone know about this problem?
Microsoft answered this question via email.
The problem happened when,
you don't have USIM card or
exhausted your data or
3G/LTE network does'nt work by some problems
Even if you are connected to network with wifi, the problem still occurs. I think Windows Phone 8.1 is always trying to process the push notification by 3G/LTE network if you turn 3G/LTE data network on.
If you can't use 3G/LTE network by given reasons, try to turn off data connection at system settings. Then push notification will be proceed via wifi network.
And they said, this is not going to be fixed even in Windows Phone 8.1 GDR2. Could be with Windows 10.
I had this problem as well and the answer above fixed it.
Just want to add that there might be a problem with roaming as well. I´m working in another country then my own and I got this problem. So if the three points above is ok, check that you are not using data roaming.

WebBrowser control and HTTPS in Windows Phone 8

I am developing my first Windows Phone 8 Application. I have requirement to load facebook login page in WebBrowser control. I am facing an interesting issue now, When I test the app in my device. Links with https is not loading, it loads a page saying "We're having trouble with this sites security certificate" etc.
Does anybody face similar issue ? Do I need to make any settings in my application in-order to access https sites ?
Thanks in advance,

I found an answer from Ben and it useful for u to solve the problem
trusted companies issue secure IDs to websites
There's a couple possiblities here:
1) If you get the same error acessing the site on other devices (make sure the URL says https, not http), it means it's the sites problem. Your phone is warning you that it doesn't trust them- for all you know, you're not actually connecting to the site at all.
2) If you don't get the same error on other devices, it means that your phone somehow lost its list of trusted ID issuers. There is a way to add certificates back, but it's probably easier at this point just to wipe the phone and restore it to factory settings.

File upload error in Django

Currently working on a site built in Django and i'm getting an issue when they try uploading a file on there PC. In IE it says 'HTTP error' and in Firefox it says 'IO error'. They are using IE 8 and the latest version of firefox with Windows media edition.
It's only on this PC they are getting the issues so i can't see how it would be a permissions thing. Just hoping someone can point me in the right direction.
Thanks,
Just checking you mean its a single computer just having the problem Quote"It's only on this PC they are getting the issues".
Compare the differences between this pc and the other pc that are successful.Your right it probably isn't a permissions problem on your serverside, but it may be a security problem with this pc in question.many things could cause such errors:
Are your successful computers have any differences from window browsers, eg:Mozilla, Chrome ect...Firewalls, User control settings on the computer?
Its hard to Conclude as companys put custom restrictions on their machines.
and the information you have provided doesnt explain depth.
Also check your error logs on your server through ftp, this may give you an indacation why this task is not successful for the pc in question, theres many factors to consider, have a look and let us Know how you go, also if you manage to solve this please leave an answer for others.
Does PC mean client or server? Are you sure the path you are uploading to exist on the server?
