lost connection to server at 'reading authorization packet' system error 0

We have recently went through the process of updating our the minor release on my HeidiSQL. The latest version seems to prevent us from connecting to any My SQL 8 clients. We can still connect to the 5.7 servers.

We've tried downloading the 8.4 library but we were still unable to connect.

We noticed a recent comment around HeidiSQL still using old offsets which have been deprecated in MySQL 8. Has a fix been released for this? as we downloaded the nightly installer and this still hasn't resolved.

If the title bar in your HeidiSQL app shows a version 12.7.0.6861 or higher then you have that mentioned bugfix.

Some more details from the connection setup would be helpful. For example usage of SSH tunnel and/or SSL.

We are currently using SSL. Please find attached a screenshot of the existing settings. Has a fix been released?

In that case you should defintely not use libmariadb but the newer libmysql:

I was thinking you already tried that?

we've tried libmysql-8.4.0.dll but that didn't resolve the issue. Is there a workaround?

Is the error message is still the same, or?

Do you always get that error, or is that sporadically only? If you once get a connection, probably this is relevant for you: https://dev.mysql.com/doc/refman/8.4/en/error-lost-connection.html

Getting this error. Lost connection to server at 'reading authorization packet', system error: 0

error is always the same unless we disable SSL in the advanced settings

@mfarag if not done already please update to v12.8, and play with the new verification option in the SSL tab.
