Problem getting work, 155.247.166.220 HTTP_SERVICE_UNAVAILAB

[tulanebarandgrill]

My FAHClient has stopped folding several times in the past week.

I keep getting strange errors with various servers but the most repeatable one is 155.247.166.220, which shows on the server status page as DOWN currently. If I browse to it I get the HTTP_SERVICE_UNAVAILABLE message.

In addition I've been seeing "BAD GATEWAY" messages to the stats page but that is intermittent. Rebooting doesn't help. Different client doesn't help. I'm not blocking any sites.

This is the section where you can see trouble:

It seems the client doesn't know what to do next if it cannot contact the server; repeated attempts fail and it always goes back to that server.

Ideas ?

Are you using a Fritz-Box-Router to connect to the internet ?

Here is a snippet of what I am getting:

20:30:15:WU00:FS00:Connecting to 65.254.110.245:8080
20:30:16:WU00:FS00:Assigned to work server 155.247.166.219
20:30:16:WU00:FS00:Requesting new work unit for slot 00: READY cpu:8 from 155.247.166.219
20:30:16:WU00:FS00:Connecting to 155.247.166.219:8080
20:30:16:ERROR:WU00:FS00:Exception: 10001: Server responded: HTTP_SERVICE_UNAVAILABLE

Eiither the server is down or is out of service or is having heating problems. PROABLY overload like that, but possibly being loaded with new WUs.
