I've change log level from notice to info and there's indeed one new message
related to HTTP/2 problem.
2020/08/20 15:59:31 [info] 32305#32305: *1982005 client timed out (110:
Connection timed out) while processing HTTP/2 connection, client: XXX,

error:1409F07F:SSL routines:ssl3_write retry) while processing HTTP/2
connection, client: XXX, server: XXX:443
