[Rspamd-Users] proxy; fuzzy_check_timer_callback: got IO timeout with server fuzzy1.rspamd.com:11335(135.181.136.158:11335), after 1 retransmits

[Thomas Robers]

Hello all,

I'm using rspamd on two mailserver similar configured. The difference
is that they are in two different networks.
On one server the fuzzy hashes from rspamd.com got downloaded and
on the other one not. Error messages like the one in the subject
appear in the rspamd log file (this does happen on both server).

rspamc on the server that works shows:

> Fuzzy hashes in storage "local": 243
> Fuzzy hashes in storage "rspamd.com": 2808787529
> Fuzzy hashes stored: 2808787772

on the one that doesn't work:

> Fuzzy hashes in storage "local": 243
> Fuzzy hashes stored: 243

On both server the connect to e.g. fuzzy1.rspamd.com does work

server one:
> nc -vz -u fuzzy1.rspamd.com 11335
> Ncat: Version 7.70 ( https://nmap.org/ncat )
> Ncat: Connected to 135.181.136.158:11335.
> Ncat: UDP packet sent successfully
> Ncat: 1 bytes sent, 0 bytes received in 2.03 seconds.

server two:
> nc -vz -u fuzzy1.rspamd.com 11335
> Ncat: Version 7.70 ( https://nmap.org/ncat )
> Ncat: Connected to 135.181.136.158:11335.
> Ncat: UDP packet sent successfully
> Ncat: 1 bytes sent, 0 bytes received in 2.02 seconds.

Blocking because of to much queries shouldn't be the problem either.
There are no FUZZY_BLOCKED messages in the log file - we have
about 2k Messages per day. Both server run for almost one month
and the one with the errors has no successful connect to fuzzy1.rspamd.com
or fuzzy2.rspamd.com. Is there something I'm missing? Can someone
tell, where to look, what to do to get this to work? Any help is
welcome.

Many thanks!
Thomas
