aiohttp.client_exceptions.ServerDisconnectedError

[d081422]

When I executed the following code
async with ClientSession() as s: client = ChClient(s,url='http://192.168.1.90:8123/',user='algorithmrw',password='dd',database='dd') alive = await client.is_alive() all_rows = await client.fetch("SELECT * FROM phalgorithm.DataAnalyse")
I ran into this problem “aiohttp.client_exceptions.ServerDisconnectedError”.

But,when I execute the insert statement, there is no problem

@d081422 thank you for the issue! But you gave too little information.

Can you tell more about engine/schema/settings of you database. Something that can give me possibility to repeat the issue?

Also it feels like it is a problem with db settings. Does it works with another clients (console or other connectors)?

Does $ curl 'http://localhost:8123/ping' works?

For anyone who also encountered the same error, it could due to the CPU blocked code before the query execution under the session which should be moved out of the session. I know it is not the reason for this issue, but the error raised is the same.
