[Icecast] mount points down in relay after a network problem

Hello.

I have a problem in a master-relay scenario.

Sometimes, when a stream is down in master server and after a while the
stream is fine again (e.g. after a network problem), relay/s server can't
get the stream again, so I have to restart icecast in relay server to make
it work:

1- An incoming stream is stopped in icecast master
2 - The stream is up again in icecast master
3 - Relay server has the mount point up but is not possible to play
(timeout error when playing)
4 - When source-timeout is reached in icecast relay, relay server
does source_shutdown in each failed mount points. Then when I request a
mount point it gives a 404 error and I have to restart the service to make
it work

Relay server has the following config:
<master-update-interval>15</master-update-interval>
So each 15 seconds the relay server goes to check the stream in the master
server

Master Server has the following config:
<source-timeout>180</source-timeout>
So it has to be 3 minutes without stream to delete the mount point.

Why the relay server does not respond after the network failure and before
the source-timeout?
Why the relay server can't find the mount points after the source-timeout?

Are there any way to force the relay server to check the mount points in
master server to avoid a restart?

This is the master config:
