I've been testing websocket client and server with Dart. Basic concept comes from Seth Ladd's blog:
Server: http://blog.sethladd.com/2012/04/dart-server-supports-web-sockets.html
Client: http://blog.sethladd.com/2012/07/simple-dart-websocket-demo.html
Everything works as expected ie. server responds clients requests and if I open a new Dartium window both clients works. When I close a client window it closes related connection (onDone:).
If I hit the refresh-button in Dartium, server raises an exception and closes. The error code is: "SocketException: Write failed, (OS Error: server closed connection, errno 10053, address = 127.0.0.1, port = 8080".
Is this a bug or should I add some code somewhere? I can't find the place where this error comes from. The last message I can find by debuging is onDone: (same as when closing the client).
Could be releated to this issue. The comments mention that it should be fixed in next release on monday.

Say, you have a webserver that you access with Chrome.
The webserver does not provide a valid certificate, so Chrome will show up the warning:
In addition, the server receives an alert which indicates this error back to the server:
error:14094416:SSL routines:ssl3_read_bytes:sslv3 alert certificate unknown
This alert is fatal for the connection, so the server closes it down.
But does anyone know how the exact behavior is after you click Advanced → Proceed to localhost? I'd expect that the error message sslv3 alert certificate unknown is no longer sent by the browser, but I can see spot it in the server's traces. This error leads to closing of the connection. However, not all connections seem to be closed: the website is loaded properly.
Is there a fall-back such as "use only 1 TCP connection for this server" or the like? What does Chrome exactly do after you accept the risk?
I'm not interested in fixing the certificate errors. I just want to know what does exactly happen between client and server after you hit Proceed to localhost.
I am writing this from my mobile, So I keep it short. After installing Avast Free Antivirus, I cannot open the Stackoverflow webpage anymore, I get the Error "Server Error in '/' Application. Runtime Error. Description: an Exception occurred while Processing your request.additonally, another Exception occured while executing the Custom Error Page for First Execution. The request has been Terminated. Help, i am a total web noob :(
I solved this by following this guide:
https://answers.microsoft.com/en-us/msoffice/forum/msoffice_o365admin-mso_other-mso_o365b/server-error-in-application-cleared-my/78b3a5d6-78d4-4c42-8a0f-638fae7c9fb7?auth=1
1.Open your browser (such as Chrome) -> use Ctrl +shift+ delete to clear all browser data again.
2.Go to Control Panel > User Accounts > Credential Manager > Windows Credentials > under Generic Credentials, remove all credentials.
3.Open Chrome and check the result again.
same problem happened!
Just use proxy ultrasurf extension! (Any other proxy also will work) No need to delete any certificates or credentials.
In case you delete any certificates or credentials it might cause some errors in future(some applications may crash).
I'm currently creating a web application through linux OS (debian), using php7, codeIgniter 3, Nginx and Mysql.
Few months ago, all my PHP errors used to be reported in the default nginx log error (located at : /var/log/nginx/)
But recently, I have configured CodeIgniter in purpose to report those errors inside the folder of my application.
It seemed to work, because I noticed that my current errors were repported in this new log file.
However, "some" errors don't seem to be reported. For example, I have a form in my web application, running aswell with Javascript (ajax use). Once I send the form, I can notice in my browser's console an Error 500 (internal server error). However, this error is not reported in my error log file ! (and I already checked in the former log file belonging to Nginx, there's nothing too)
What am I supposed to do ?
Thanks you.
Attempted to add a project from a server on a remote host. I can SSH & SFTP without PHPStorm in no prob. The first error I encounter is attempting to select my remote server; when I test the connect, it is successful. When I do not check off 'Don't check HTTP connection to server', I get:
Connection to 'Server' failed.
HEAD method failed for "ip address" with HTTP status 401.
If I enable Don't check HTTP connection to server, I can proceed and I am brought to a list of all directories on my remote server. I select my project as the project root, and attempt to download. Collecting files goes smoothly, and downloading goes by well until a particular file is reached. Error msg:
Downloading Project Files failed: failed to transfer file 'wireframes.scssc': channel is not opened.
I tried to exclude that directory from download, but it had no effect.
The apache server is configured with basic access authentication. I disabled mod_auth_basic (as confirmed in php.ini), but am still prompted for credentials even after an apache restart. This is second issue preventing me from exploring this potential solution. Any suggestions?

I had this same issue, to fix it I chose custom for deployment options and then added .sass-cache to the list of things in the "Exclude items by name" field.
I also had to close and re-open phpstorm or it would fail immediately after starting the download.
I have a Point of Sale System developed by a local developer and I keep getting this error. The error results when I am using the program and hit the next button to display the next list of items in the menu. The program just crashes and closes when this occurs. The Program works though a mysql database that is running on the same computer.
Heres what my event viewer reported on the error.

The certificate received from the remote server has not validated correctly. The error code is 0x80092013. The SSL connection request has failed. The attached data contains the server certificate.
