I have a Symfony 4 application running on 1und1 on a package called "1&1 Unlimited Plus". The SMTP config looks like this:
MAILER_URL=smtp://smtp.1and1.com?username=****&password=******
and it works fine. I also have a development copy of this application on my local dev server with same config. This dev copy can send emails, too.
Since the databases on "1&1 Unlimited Plus" are limited to 1GB, I ordered another cloud server from Ionos. With the same config I am not able to send emails. I got this error in dev.log:
Exception occurred while flushing email queue: Connection could not be established with host smtp.1and1.com [Connection timed out #110]
Ping on smtp.1and1.com works, it reveals the same IP like if I ping on my dev server. On this cloud server I have running:
Plesk Onyx
Ubuntu 18.04.2 LTS‬
DNS turned off. I have just an A-record on the origin server to the IP of cloud server. NO MX-records set.
I checked the firewall rules. No outgoing limits found, just incoming. I added TCP 25 to incoming rules but I dont know if it is necessary.
I tried another ports but then I got this:
Exception occurred while flushing email queue: Expected response code 220 but got an empty response []
More config:
swiftmailer:
url: '%env(MAILER_URL)%'
spool: { type: 'memory' }
Any idea whats wrong?
I found the solution. Ionos closes the outgoing port 25 per default. This is nothing I can find or change in admin area, only technical support can open this port.

I have a very curious issue with an application. When debugging locally, I can send emails just fine using a client's G Suite email credentials:
<smtp deliveryMethod="Network" from="client#customdomain.com">
<network defaultCredentials="false"
host="smtp.gmail.com"
port="587"
userName="client#customdomail.com"
password="supersecret"
enableSsl="true" />
</smtp>
Now, it's very important to note that the application will send just fine with the credentials when running on localhost using Visual Studio. However, when deploying to LIVE and using the exact same credentials, the application refuses to send and I only get the canned response back saying "Failure Sending mail".
I have enabled "less secure applications" in the settings and have verified the "suspicious activity" from the server's IP address. I can also log in to the Gmail account from the server using RDP and opening Firefox to go to Gmail.com.
No firewall rule has been set to block SMTP or anything on port 587.
UPDATE: the materialized error message is
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 74.125.192.108:587
74.125.192.108 being smtp.gmail.com's IP Address (or one of them, at least)
UPDATE 2: I can also not get Thunderbird on the remote server to send an email using the supplied credentials, however it can connect via IMAP and download the contents of the inbox just fine.
Well in this very specific case, it was the fault of the Amazon infrastructure this application ran on. Either amazon themselves, or the reseller changed a policy that ended up blocking communications on ports 465, 587 and 993 (and probably others too).
The "solution" was to nag them to sort it out.
I created an instance (CentOS7) in GCE. I then installed Glassfish 4. However, I can't seem to access it via http/https.
[ank#instance-1 bin]$ sudo ./asadmin start-domain
Waiting for domain1 to start .........
Successfully started the domain : domain1
domain Location: /opt/glassfish4/glassfish/domains/domain1
Log File: /opt/glassfish4/glassfish/domains/domain1/logs/server.log
Admin Port: 4848
Command start-domain executed successfully.
When trying to access http://ip_address or even http://ip_address:4848 I get "refused to connect" error.
Appreciate any help.
you'd need to open port tcp:80, tcp:443 (and tcp:4848) on the firewall; assuming you have already assigned an external IP (or are accessing it from another internal IP on the same network, which I'd suggest for tcp:4848). see the documentation, concerning: Using Firewall Rules.
i'm having a problem sending the mesurements to the contextBroker.
I have the ContextBroker running on a CentOS virtual machine. On another CentOS virtual machine i'm setting the figway config.ini file with the host=/ContextBroker Virtual Machine Host IP/ and Port=1026. When i send mesurements to my ContextBroker:
python2.7 SendObservation.py Bus1 't|1'
it simply doesn't stick the values to the entity. It gives me a code:200 but the response is just blank.
What am i doing wrong?
UPDATE:
Even when i do from one VM to another (to the one where the contextBroker is running) the command:
GET *ip*:1026/version
, it returns nothing.
UPDATE:
Running
GET localhost:1026/version
works. Returns what's supose to return.
The problem could be similar to the one described in the answer to this question. The most probable causes of Orion connection problems are:
Something in the Orion host (e.g a firewall or security group) is blocking the incoming connection
Something in the client host (e.g a firewall) is blocking the outcoming connection
There is some other network issue is causing the connection problem.
I am trying to get the MAC client app to sync files and enable port forwarding.
When I turn on port forwarding I get "Port Forwarding Error: Authentication failed."
When I turn on File Sync I get "File Sync Error: Lost connection with the server"
I can see my boxes in the client app and tell when they are running or not.
Any help with this issue would be appreciated.
Worked with NitrousIO tech support and it was an issue with ssh keys. They had to delete my keys on their end and register them again.
If this happens to you, you will want to contact support.
We have a small network behind a firewall (WatchGuard XTM 2 series) and network switch. On our network we have multiple instances of SQL server, but 1 in specific that I would like to be able to access remotely from our website. We have a static IP address from our ISP and then all the machines on the network have a locally assigned dynamic IP address. When trying to connect to the database from outside our network how do I get the request to be directed to the proper machine / SQL instance? Is it a parameter in my connection string or something in my firewall?
A few things to rule out:
1) The firewall is allowing access from the website to our network. I added the site's IP and opened up port 1433. Also, when trying to connect and monitoring the firewall no exceptions come up as they did before I added the proper IP address.
2) Remote connections on the SQL server has been setup and enabled. I've done a lot of reading up on remote connections and I am sure it has been setup properly.
I am currently getting this error message on my site:
A network-related or instance-specific
error occurred while establishing a
connection to SQL Server. The server
was not found or was not accessible.
Verify that the instance name is
correct and that SQL Server is
configured to allow remote
connections. (provider: TCP Provider,
error: 0 - A connection attempt failed
because the connected party did not
properly respond after a period of
time, or established connection failed
because connected host has failed to
respond.)
The Server parameter of the ConnectionString indicates what server to connect to. Assign an ip address or URL to the server that you want to access and put that in your connection string.
