Same here on Mac OS 15.6 Desktop app. PgAdmin version 9.7

Hi All,

Sure, we will verify it. Just for your information, we haven’t made any changes to the SSHTunnel logic. It looks like the Paramiko package released a new version (4.0.0) on August 4, 2025.

Same here. Can we downgrade pgAdmin as a temp fix?

I have the same issue, similar setup. Was fixed by downgrading back to 9.6

@Orrison I am having the issue in version 9.6. Hmmm, can I even downgrade pgAdmin since I installed it with PG 17.6? For now I have been just doing ssh port forwarding in Powershell.

Oh sorry, I mis-read this all. I am on Mac OS. Not sure if that makes a difference
