After download .deb , installing binary and running semaphore program standalone (not in docker) - ssh key added flawlessly.

Is this still on-going issue for docker? I also can't create a password in Keystore due to:
time="2025-12-06T13:23:45Z" level=error msg="illegal base64 data at input byte 5"

i got this encoding error (400 bad request status) when i had a wrong value of SEMAPHORE_ACCESS_KEY_ENCRYPTION in my env file (it was missing a character...). Semaphore uses this key to encrypt sensitive data stored in its database (access keys and secrets). Hope this helps someone out-there.
