FTPS fails when SSL cert changed on server

FTPS has been working fine for many months. The SSL cert on the server was updated as the original cert expired. Now PHPStorm fails to make FTPS connection and the log shows the cause is the SSL cert has expired. The expiry date is the old cert that has been replaced on the server.

Does PHPStorm cache SSL carts? If so, can that specific cache be purged?

Not really. As a thing to try, you can rename the PhpStorm configuration folder, start PhpStorm not importing previous settings, create an empty project and try to connect from there.

If it's still bad, please revert to your initial setup, enable extended deployment logging, reproduce the issue and collect the IDE log.

Thanks for your reply. In fact I have just resolved this issue. I could indeed connect from WinSCP, but not from PHPStorm. When I dug into the logs for the WinSCP session that would connect I discovered that it was also getting the expired certificate from the server... it just ignored the fact! So, PHPStorm was behaving impeccably, and the other FTP program was not. Armed with that information I went back to the hosting company and they accepted the problem must be their end. After a bit of searching they found the problem and fixed it.

Wonderful, many thanks for the update.
