I would suspect the new SR1 receiver first. Have you a third receiver that you could substitute to test this? Has the new receiver been set up correctly? There is a clear disconnect at the receiver substitution and it is unlikely that the dish alignment got disturbed coincidentally.
Best of luck!

We have an EUMETCast Linux reception station that has developed a fault on the
Ayecka SR1 DVB receiver last month. Having replaced the SR1 receiver, we are now
able to collect all the basic services data, but only a tiny fraction of the high volume services.
Typically, we are getting the hvs-1/EPS1, EPS2, EPS5, EPS10 data during the hour
between 06:00 and 07:00 but almost nothing outside that period.
Ironically we had been getting the full hvs-1 data without issue before the breakdown on the SR1.
Currently the signal Demodulator Es/N0 is about 9db.
Before attempting the option of adjusting the dish pointing on site which being locked down,
I wonder if any one has any advice that we can try to improve the hvs1 data reception.
