Google Photos returns 401 after Authentication Successful

Please try the following steps:

1. Create a post with the following shortcode:
   [gallery type='google' view='albums']
   I am assuming that your shortcode is gallery. If not, substitute gallery with whatever your shortcode is.
2. Save the post and let me know what the URL is.

I can take a look at the post once you have done so.

Ok, this is the link (you need to put the password to see the post: TestPhotonicPlugin)

This is what it says…

Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.

OK – this is one of those issues that is a plugin conflict, or a host setup issue (it is a little hard to say which one it is).

Basically what is happening is, something at your end is removing the OAuth token from the request. In the past this has been seen to happen due to:

1. Settings made by your web-host to prevent HTTPS calls from your domain
2. Security plugins that strip out parameters on outgoing calls
3. Caching plugins that remove URL parameters assuming that it will help with caching

I would suggest checking with your web host first to see if they have any setting preventing HTTPS calls from being made by cURL. If not, then ask your host if they can see what outgoing calls are being made by your domain.

If your host is not able to determine what is happening, then deactivate any sort of caching plugin and security plugin to see what is happening.

Thanks for your suggestions. I’ve been playing with DNS and trying to grant https access, but none of the changes I tried fixed it… Then I went through some other replies you posted on other threads and tried to use a previous plugin version (2.34 instead of 2.43), and the previous version made the magic!
I am using php 5.6, because I use a VM from google cloud and cannot upgrade to any posterior version (not at least with the configuration I am working with, I already tried it).

Thank you again for your quick response ??

Hmm… while I am happy that it worked for you, this is unprecedented. I didn’t make any changes between 2.34 and 2.43 for authentication, so the results are quite puzzling. Let me scrutinize the code further to see if there are any differences in between how the calls are happening. Let me also see if other users facing this issue are on PHP 5.6 and if downgrading to 2.34 fixes the issue for them.

Ok, I will keep an eye on your responses. Thanks again

Can you tell me how you installed 2.34? Did you go to your WP Dashboard → Plugins, then “Deactivate” Photonic, then “Delete”? Did you upload the older version after that?

If you did so, I have a hunch that the “Delete” step probably flushed out a bad setting that was preventing this from working, and that now if you upgrade you will be fine.

Yes I did that first… I was reading your reply on the other thread and it all makes sense now ?? I’m glad you found the error & the fixing.

I confirm I just tried deactivating & deleting 2.34 and reinstalled 2.43, and everything woks with the latest version. Thanks!
