Still problems connecting to teamviewer server

I can reach the masterservers on all three ports (80, 443, 5938), but I cannot connect to any of our PCs.
I get an errorcode of 10054 in the log.
Any suggestions?

    I'm on Team Viewer 9.
    I haven't been able to connect to the server for nearly 24 hours now.  It comes up with the 'Most likely you use a proxy server' message. It was running fine yesterday afternoon and I've used it every day for years now. Same computer, same setup, same connection. No changes at my end.  What's going on?  Did you bungle the maintenance you did on Sunday?

    Is this the Problem ?

    DNSBL checking the result of IP

    rDNS found:

    • <> valid FCrDNS.

    This IP has been blocked, but it's reputation is not bad anymore.

    Hi @JoSte,

    Thanks for pointing that out - but no, that's definitely not related to the connection issues being discussed here. DNSBLs are used by some mail servers as a means to block spam from disreputable sources, and being listed on one - in this case, a small, not-widely-used BL based in Brazil - would have no effect on the ability of the TeamViewer software to connect to our master servers.
