1st request to a inactivitytimeout disconnected reader always fails with timeout

Issue Description

1st request to a disconnected, due to inactivitytimeout, cccam reader makes it auto reconnect (as it should), but that 1st request always fails with timeout

When the issue occurs

Always, and I did test with a few different cccam servers with same results... also it's not a new issue, I can reproduce it for long time on different revisions... for some time I workaround it having reader always connected, but now I thought I should report it...

How the issue is reproducable

This is very easy to reproduce, I think anyone should be able to reproduce it easily... anyway if you really need debug log I will post it for sure.

I reproduced it on multiple systems, but for test purposes I tried it on a pretty clean oscam config (lb_mode=1, all the rest almost all default except reader configs), with just one single cccam reader (with inactivitytimeout=30) and this is what happens:

I should say that similar config with newcamd reader works perfectly, 1st request after auto reconnect succeeds, problem happens only with cccamd readers...

I did also research if there is at least a config that makes oscam retry a request after timeout (despite that would be a workaround), but strangely there isn't... after timeout oscam completely stops trying completely until next ecm... I don't see a config to change this... I did also found ticket #2659 about that... my only solution to avoid this issue is having reader always connected 24/7...
