Algo Forge authentication issue

[Toh4iem9]

Hello,

I’m unable to use the forge.mql5.io repository through MetaEditor. It was working without any problems until recently — push, pull, fetch, and all other Git operations were successful.

Now MetaEditor shows:

2026.09.11 19:50:18.766    Git    MQL5 Algo Forge activation failed [401]

When I try to use Git from the terminal, I get:

git fetch --prune --all

remote: Credentials are incorrect or have expired. Retry your command or see https://codeberg.org/forgejo/forgejo/issues/2809 for more information

fatal: Authentication failed for 'https://forge.mql5.io/Toh4iem9/mql5.git/'

I also installed a completely new MetaTrader client to rule out a local configuration issue. Even the initial activation fails there:

2026.09.11 20:12:57.408    Git    MQL5 Algo Forge activation failed [401]

2026.09.11 20:12:58.205    Git    250 public projects found

So it looks like the problem is related to authentication on the Algo Forge side. Could you please check what might be causing this?

Thank you!

Make sure that your mql5.com login and password are entered in the community tab of the options.

If you don't mind working with Git solely via the terminal, you can authorize the application by re-entering the command.

On the second or third attempt, a browser window should open, allowing you to authorize by clicking the "Authorize Application" button.
