OB SERVER invisible to multi thread instance but ok with Single thread?

[Uteman]

Hi people,

I am hoping there is a simple explanation for the heading. I know enough about networks and routers to stuff things up and get confused.

I am running my server on a dedicated separate PC on my home network. About 2 weeks ago my multi thread instance on the client PC stop seeing the server whilst the single thread instance continues to see it just fine.

I have reinstalled the server software and client after cleaning the PCs and it runs just fine when I log into it (single thread) from the client PC. Can see all the other Public servers when I search and can join public (no PWDs) servers no issue. When I search with Multi Thread instance my server is nowhere to be seen.

Versions of OB are the latest, and obviously the firewalls  are ok ( I didn't change the settings) as the single thread can see the server ok.

My ISP blocks some ports but not 10308 and 10309, if they did logically the single thread client wouldn't work either.

All of the Forum threads I have searched suggest multi thread should (and it used to) work fine with OB server.

Looking for some help from somebody who can shed some light on this problem?

Thanks

Uteman

What happens if you click connect by IP and manually insert IP and port on the MT client?
Times to time it happens that server hosted in the same subnet (LAN) is not visible by client, but I believe is more related on how the router is handling the routing table from/to your public IP etc. ( like the "problem" of SSL services that you need a NAT loopback feature to use from other clients if you don't edit client hosts file and how it resolves DNS )

Did you change the router recently maybe?
