Hey

I try to connect to Dropbox to authenticate for post processing.
Wenn I hit Authentication - Start here, the new window opens as usual, but instead of the keys I get:

Die Webseite unter https://www.dropbox.com/1/oauth2/authorize?client_id=ywdzltblj1rzj6y&response_type=code&redirect_uri=https%3A%2F%2Fwww.akeeba.com%2Foauth2%2Fdropbox2.php&state=%7B"return"%3A"https%3A%5C%2F%5C%2Fmorgenbrodt-pipes.de%5C%2Fadministrator%5C%2Findex.php%3Foption%3Dcom_akeebabackup%26view%3DConfiguration%26task%3Ddpecustomapiraw%26engine%3Ddropbox2%26method%3DoauthCallback"%2C"dlid"%3A"62072%3A94b14aa5c673e8f33588dc7eb1edbc7f"%7D&scope=account_info.read%20files.metadata.read%20files.content.write%20files.content.read%20team_data.member&token_access_type=offline ist eventuell vorübergehend nicht verfügbar oder wurde dauerhaft an eine neue Webadresse verschoben.

ERR_HTTP2_PROTOCOL_ERROR What to do? Thanks Rolf

The URL you are trying to access is hosted by Dropbox, not us.

Moreover, I can open the URL just fine with Google Chrome and Firefox both on my desktop (Arch Linux) using my regular ISP, and my smartphone (Android 16) using my mobile provider.

This is very likely a problem coming from your device or your ISP. Please check if you have any browser extensions, script / ad blockers, custom DNS providers etc which might be interfering. Moreover, make sure that you can access https://www.dropbox.com from the same browser on the same device.

hey
Thanks. Calling it up directly worked here as well, also Dropbox access is no problem. Maybe a glitch at the Dropbox site? Anyway, I got the keys and all seems to be working.
Thanks

Either that, or a glitch in the DNS server you are using. The message returned by the browser is ambiguous. It could mean either a DNS issue, or a network issue. The past 10+ years the browsers have "simplified" the error messages to the point that they are completely useless for the user and the person doing support as we get the same error message back from the browser for completely different issues with radically different solutions.

hey

hmm, it seems something isn't working. I did run the back up yesterday, and it worked and uploaded to Dropbox.

Today I got:

- Failed to process file /var/www/vhosts/h265060.web66.alfahosting-server.de/html/2025/logs/site-morgenbrodt-pipes.de-20251110-065904utc-mGmeu1w3zfmnuXVQ.jpa
- Error received from the post-processing engine:
- You have not linked Akeeba Backup with your Dropbox account
- Post-processing interrupted -- no more files will be transferred

And indeed, the file isn't in the Dropbox.

Any ideas?

Thanks

You have not linked Akeeba Backup with your Dropbox account

This means that you have not gone through the full authentication step in Akeeba Backup.

Can you please try using a different browser and device? Until you get a valid Refresh Token and copy it into Akeeba Backup the upload to Dropbox will not work.

Thanks

It worked once...
I have done as you suggested and the first backup worked again. Now we have to wait until tomorrow...

Thanks

As long as you have a Refresh Token and you have not tried to use it with a different backup profile or site it will work.

As I hit sent I realised I didn't explain this properly. You can of course use the same Dropbox with different backup profiles and sites. BUT! You have to use the authentication button on each backup profile to copy a different Refresh Token into each backup profile (on the same or different site). Otherwise, the first profile to use the Refresh Token will work, and every other backup profile will fail to use the now possibly invalid Refresh Token to fetch a fresh Access Token. This is a limitation / security feature of Dropbox' OAuth2 implementation.

hey

I had both yesterday and never used in context with other sites and it worked once...

Yes, I realize what you are saying in your second post. I have a couple of sites using Dropbox in the post processing without troubles.
Let's wait and see :-), I think it should work.

Cheers

Rolf
