error hosting zombie server

[andresito_20]

in zombies i cant host my server i get this error

but in multiplayer if my server appears and that I don't have port forwarding in my router and if multiplayer people can connect, but in zombies the server doesn't even appear because of this error

andresito_20 i see no issue in that log, "session create error 0" is normal. did you change the port for your sp server so it's different from your mp server and also made a rule for it in your windows firewall?

The same thing is happening to me too, I have configured portforwarding and it happens to me
