Algo Forge authentication issue

New comment
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!

### Description Whenever I do `git push` or something that requires authentication, it fails the first time. Repeating the same command makes it work, and it keeps working for a while after that. Attached below is a screenshot of how it looks. I'm using `git-credential-manager` for `https` auth....

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.

AlgoForge -> IDE error

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

I am logged into my MetaEditor Community account, but activating MQL5 Algo Forge still fails.

Here is the relevant output from the MetaEditor log:

2026.09.12 00:14:00.481    MCP    started on 127.0.0.1:22345

My MetaEditor version is:

Version: 5.00 build 6182


I can also successfully log in to both mql5.com and forge.mql5.io using the same username/password combination.

I found the following forum post, which seems to describe a very similar issue:

The user is unable to log in to AlgoForge using their MQL5.com credentials, suspecting a password synchronization issue or account registration conflict. They have tried password resets and confirm they can log in to the MQL5.com Community tab. They request assistance from AlgoForge support to resolve the login problem.

Thanks! In the meantime, I’ll switch to doing Git manually. Good luck tracking down the issue! 🙂

Please check you are using the same password to connect to mql5.com and forge.mql5.io as you are using with MT5/MetaEditor.

Please check you are using the same password to connect to mql5.com and forge.mql5.io as you are using with MT5/MetaEditor.

I am using the same username/password combination on all three platforms:

- mql5.com
- forge.mql5.io
- MT5 / MetaEditor

I believe MT5 is properly connected to my MQL5 account, as the account messages are displayed there.

However, MetaEditor is still unable to connect to Algo Forge. I am getting the following error message:

2026.09.14 17:29:42.082 Git MQL5 Algo Forge activation failed [401]
2026.09.14 17:29:42.923 Git 250 public projects found

I use two-factor authentication on Algo Forge, but this has not caused any problems with MetaEditor in the past.

At the moment, I am manually uploading and downloading the files using Git.

Did you happen to change your account password?
I had a similar situation about a year ago after changing my password. But as far as I know, that was fixed a long time ago.

A MetaQuotes developer reported it as fixed, please confirm.
