Error 504 (timeout) during loading of images.

[joshuabeny1999]

Hello,

I created a docker-image for nanogp2 (https://cloud.docker.com/u/joshuabeny/repository/docker/joshuabeny/nanogp2).
But the issue has nothing to do with this. It was already in my old installation. I tried now with the docker image to run nanogp2 on an own subdomain because I use it for more than one website. So I tested a new installation with the latest version of nanogp2. But this seems not to resolve the issue.

The authorization of the accounts works perfectly. But if I want to use any google album with nanogallery2 it loads 1 minute and afterwards following error Message appears:

In the developer console of the browser, I see an error 504 - Gateway Timeout.

In the logs.txt it is really strange that it always tries to obtain a new access token for a minute.

I already tried to revoke and reauthorize my user. This didn't help. I also tried another google account with only a few albums, but this one also did not work.

I hope you could help me fix the issue.
