Unexpected EOF from the server (SQL server) #98

Open meichengg opened 2 months ago

meichengg commented 2 months ago

Detailed error description

Hi, i have used v3-v5 but all gave me the same result when i tunneling and connecting to MSSQL server, sometimes when clicking on some random databases, random tables, it shows me this error then it crashed the connection to the DB, i had to reconnect but same thing happened again. I have tried to switch to other DB management apps but nothing changed.

Observe the output and it is running normally. It is recommended to use other tunnel tools to test whether the server is normal.

meichengg commented 2 months ago

Can you try on your end using DBeaver to connect to the database?

meichengg commented 2 months ago

Here is the error when Test connection to DB with the MSSQL account through the tunnel.

[ERROR   ]  [FORWARD] [10.0.115.15:1433] HTTP [200]: Status: [FAIL]: Message ['POST request read filed'] Shutting down

When i press retry then it behaves normal, very random errors which make it unstable.

L-codes commented 2 months ago

OK, I'll test it out when I have time.
