[DeviantArt] Error when batch uploading

I can't upload art from deviantart. When I click in "fetch" I get this error:

"
failed to fetch page (got code 403)

It only occurs on Deviantart as I can still make batch uploads from other sources like Twitter and Pixiv just fine.

Something must be up with DeviantArt, I can't even fetch source data on existing posts sourced from there. Is it an API thing?

It looks like they're blocking all server IPs from downloading posts. It will take some time to figure out a solution.

Their developer page contain basic information only.

403 Errors
If you recieve 403 errors that contain an HTML response rather than JSON, please ensure your client is sending a User Agent header and using HTTP compression for the request, we reject any requests not meeting this requirement.

If the blocking is not related to this, then it is worth considering temporarily disabling the processing of requests to this site.

Looks like it's working again. The problem was that they were blocking pretty much all cloud server IPs for a period of time, so we couldn't fetch posts without using a residential proxy to hide our IP address.

The problem was to make an API call like this:

• https://www.deviantart.com/api/v1/oauth2/deviation/56428A64-ACDF-EFE1-9D79-5C0F551F2990

We have to fetch this first:

• https://www.deviantart.com/retrogameart/art/Cronos-Resurrection-At-Death-Peak-800741733

To get the post's UUID (56428A64-ACDF-EFE1-9D79-5C0F551F2990). But fetching that URL returned a 403 error when using a cloud server IP, so we couldn't get the UUID to make the API call.
