Error in the project display

The situation is as follows: some time ago, I was added to a work project that I was working on with colleagues, after which it was decided to pause for about 2 months, all this time I periodically visited the project page and everything was fine, but for the last week I have not had access to the project, as if I had been removed from the list of developers. I contacted the maintainer to find out about the situation - he said that I was still listed as a developer of the project and had access to it. We decided to remove and add me back to the project, but it didn’t help in anyway.
Please tell me how to deal with this.
