icmp relay hangs

[FreedomPrevails]

ICMP relay only works for few minutes and then it stops working, restarting the client part resolves the issue immediately and again it hangs after a few minutes. I see no errors in the log.

Server : gost3 -L relay+icmp://:8443/:1234
Client : gost3 -L tcp://:443 -F relay+icmp://x.x.x.x:8443
Version : rc8

Edit : I also tried keepAlive option, but it didnt help.

I have the same issue when there are many connections. it just hangs and dont work anymore. Dont know if its the protocol limitation or gost bug

The same behavior is happening with forward+kcp, and restarting client service fixes the issue, I haven't found any related log yet. Any help will be appreciated.

Client service setup:
