There is a stackoverflow thread with the solution here, have you tried this? https://stackoverflow.com/questions/42485408/getting-error-of-invalid-iv-length-while-using-aes-256-cbc-for-encryption-in-nod

That’s not directly electrum but it looks like it’s with the aes encryption in general, but I could be completely wrong.

Add code to work out how big the actual inputted password is otherwise and return the results here (in bytes).

What command are you trying to run that gives this error, can you isolate it or is it in a script somewhere?

For example when calling

Code:

electrum getseed

Hello, I can open my password-protected wallet locally via GUI without any problems, but when I try to access electrum password-protected functions on server using console I get this error:

Code:

Server-side exception: >

During handling of the above exception, another exception occurred:

How to fix it?
