Can not connect to Clickhouse version 22.3.8.39

[AndreyRomanovZexxonn]

I want to use asynch library with one of the latest Clickhouse versions 22.3.8.39. Got exception

 File "/home/zexxonn/DEV/Quantor/momote/backend/app/context.py", line 81, in create_asynch_pool

    raise UnexpectedPacketFromServerError(message)
asynch.errors.UnexpectedPacketFromServerError: Code: 102. Unexpected packet from server rc1b-ceve8zbnw6zcqb0d.mdb.yandexcloud.net:9440 (expected Hello or Exception, got Unknown packet)

With Clickhouse 21.12.2.17 everything work well. I used debugger to understand difference between versions during connection and found that here https://github.com/long2ice/asynch/blob/dev/asynch/proto/connection.py#L226 for CH 22.3.8.39 asynch client receives packet_type == 21. I am connecting with ca_certs and secure=True.

How connection problem can be fixed?

It may happen if you connect to clickhouse via http port instead of TCP.
