all-in-one wp migration s3 backup 400 bad request error diagnostics
Setting up automatic backups to S3 bucket via WordPress plugin all-in-one-wp-migration extension for S3. https://servmask.com/products/amazon-s3-extension
First off, fantastic wordpress backup plugin – I’d say the best I’ve tried so far.
Added settings and set up correctly with access keys.
Now testing manually clicking run a backup and selecting S3.
Processing backup to AWS S3 bucket.

Then I get the error. “Unable to Export, 400 Bad Request”.
Checking for plugin updates.


Double check settings/auth.


Didn’t work still got the error.
I tried this again on another website which is hosted on AWS EC2 and not on shared CPANEL and it worked.


Just checking the supported hosting providers for the Plugin:
My CPANEL is with hostgator which is on the “should work” list.
Exporting to file gives me this error:

Temp Changing the permissions to 777 to see if that works.
Now it is hanging here…

To solve this delete everything in the /storage folder of the plugin except index.php
