Description

My Code:

conn = sql.connect(server_hostname = server_hostname, http_path = http_path, access_token = access_token, _tls_no_verify=True)
cursor = conn.cursor()
select_sql="select * from tableA"
cursor.execute(select_sql)

Then console show error as follows:

cursor.execute(select_sql) start : 2025-11-18 09:11:09

And Finally Got this error:

2025-11-18 09:19:18,996 ERROR:databricks.sql.common.unified_http_client:HTTP request error: Retry request would exceed Retry policy max retry duration of 300 seconds

May I ask, what are the possible solutions to fix this kind of error?
