SSH-tunnel doesn't work with PuTTY > v0.81 #2118
Description
Description
To access our databases, I need to establish an SSH tunnel with a password-protected certificate.
I've been using HeidiSQL and PuTTY for this for years.
After upgrading PuTTY to a version higher than 0.81, this no longer works. I tried v0.82 and v0.83. As soon as I reinstalled v0.81, access worked again.
With PuTTY v0.81, a window for entering my passphrase appears in HeidiSQL when establishing a connection.
With v0.83, I get an error message instead of the passphrase pop-up.
If I manually open the connection in the terminal with v0.83, I can successfully connect to the database in HeidiSQL using host 127.0.0.1.
Apparently, the necessary interaction with plink.exe has changed.
Current Setup:
- Windows 11 Enterprise 24H2 Build 26100.3476.
- PuTTY (64-bit) v0.81
- HeidiSQL 12.10.0.7024

When I call plink.exe manuelly in the console, I can't see any difference in the output between v0.81 and v.83 (screenshot v0.83):
HeidiSQL version
12.10.0.7024
Database server version
