Gitkraken says repo is private but its public

I have my repo stored on GitHub and visibility is public but since a few days when I try to open the repository on Gitgraken, it says that the repo I'm trying to open is private and it won't let me access it.

Things I have tried:

• I tried closing and opening Gitkraken.
  
• Uninstalled Gitkraken, removed the directory in AppData and reinstalled Gitkraken.
  
• Make sure that the repo is indeed public.
  
• I also tried opening the repo again by browsing to the directory rather than trying to open it from the recent projects.
  

However, it still displays that message.
I have tons of projects and that's the only project which gets this message.

Check if:

• GitKraken is using an HTTPS URL to access that repository
• if git config credential.helper is set

If other projects (under the same GitHub user account) are accessible from GitKraken, then it is not an authentication issue.
What remains could be a typo in the repository name.

Do check the GitKraken logs to see if there is any more clue.
