Please advise

Can I pay someone to help me with that?
I would need help via any platform to guide me through the process

What user is present in your espocrm-websocket.service file?
Is this user the owner of the espocrm directory and is this the user that runs the webserver (eg. www-data or apache)?

[Russ]

Uploaded web config for the domain + espocrm-websocker.service
+ cli that shows the owner of the folder (*.com-le-ssl.conf looks just like .com.conf that is on the screenshot)
Firewall: 443/8080 are opened for UDP incoming and outgoing requests

Safari:
WebSocket connection to 'wss://crm.batman.com/wss?authToken=c765ba83fc0d419e1aa0e6d16d447337&use rId=1' failed: There was a bad
response from the server. (error 500)

Please help

Also, I tried debug option..but where to try? Added to config, then to config-internal...then ran php web socket.php, nothing

>webSocketDebugMode – bool – false – if you run a server (php websocket.php) manually from CLI, you will be able to see debug messages in the terminal;

[novastream]

Maybe a silly question but have you enabled websockets in config.php and installed the php zmq module?

You can run php -m to see all installed modules.

Also isn't web and websocket using TCP and not UDP?

Thanks for your reply, php-m, attached, all loaded, both TCP and UDP enabled on the firewall

tarasm Hi! Can we get a paid support, please?

Hi Russ,

I'm not sure if this will absolutely help, but if you have time, try replacing ports 8080 with 8081 in the Apache configuration file in the next part (the part will look like this):

<IfModule proxy_module>
  ProxyRequests Off
  <Location /wss>
    ProxyPass ws://espocrm.example.com:8081
    ProxyPassReverse ws://espocrm.example.com:8081
  </Location>
</IfModule>

Don't forget to restart Apache after that and see if the previous error reappears.

Russ,

Can you please tell me if there is any progress on Websocket setup?

lazovic thanks, I tried, but same issue.
I am trying on 2 machines, Amazon Linux 2 and Centos 7

I bet it has something to do with ZMQ which does not support php8.1, but I am not 100% sure, I asked tarasm to step in with a TeamViewer session to my servers via my computer and SSH.

Hope we will be able to dig into something.

Thanks!
