Connected but number of peers constantly 0

[mihha]

Hi,

I noticed that after the computer (both Win10 and Win 11) goes back from hibernation, ClipCascade client is apparently connected to the server, but the number of peers is always 0

Only if I quit the client and start it again, it connects to peer

This connection lasts for a short time and after that, the connection is lost again

Something is breaking this connection, but I can't debug what

Can you tell me how could I debug the problem to see what is going on?

Server is behind Apache reverse proxy with the following configuration

Protocols h2 h2c http/1.1

ProxyRequests Off
ProxyPreserveHost On

RequestHeader set X-Forwarded-Proto https
RequestHeader set X-Forwarded-Port 443

ProxyPass / http://localhost:8123/
ProxyPassReverse / http://localhost:8123/

RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteCond %{HTTP:Connection} upgrade [NC]
RewriteRule ^/?(.*) "ws://localhost:8123/$1" [P,L]

I can see the following in the logs when I restart the ClipCascade clinet
