Hello everyone!

I'm working on a project with Decap CMS, which is connected to Gitlab, using the PKCE configuration to authenticate the user.

However, Decap is working intermittently. As you can see in the screenshot below, the user receives some error messages, especially during authentication.

The "token" and "user" routes are the most problematic, but other routes also behave intermittently.

The user is able to connect and use the CMS after several attempts. After these initial errors, the CMS remains stable for quite some time.

Have you ever seen a situation like this? If so, what was the solution?

Decap CMS Version: 3.8.3

Note: We've been using Decap CMS since 2024, and we started noticing this issue three weeks ago. We updated the project to the latest version, but the errors persist.
