Sometimes NMEA stops after the fix on EG25-G

Sometimes on EG25-G GNSS engine stops output NMEA messages after the first successful RMC report. That happens, when communication is done using QMI and with AT-commands as well. MSB A-GPS with SUPL from google is used.

To recover from this state GNSS engine has to be restarted (AT+QGPSEND, AT+QGPS=2).

That happens not every time, but pretty frequently.
It looks like it started after I switched from standalone mode to MSB, but not sure yet.

Is it a known issue?

The problem was proxy, that not forwarded SUPL END message to supl-client in the modem. That probably hanged NMEA stream. All works correctly without a proxy.
