[BROKEN] License Verification API Failure

I'm currently running FileBot version 5.2.1 and within the last week something has changed, what appears on your server side, FileBot fails to verify the license and will not re-name files because of this error. The failed API call is: https://license.filebot.net/verify/xxxxxxxxx. The exact application message is as follows:

Code: Select all

Server Error: https://license.filebot.net/verify/xxxxxxxxx [429 Too Many Requests]
. When I run the API call via browser I get the following error:

Code: Select all

{"status":400,"message":"Bad Request"}
. I replaced my real license number with xxxxxxxxxxx for this post, this was not the data sent to the API call.

Will you please fix!
Steve

:?: Which VPN service are you using?

:arrow: Please disable your VPN, or use a different VPN server, as your current shared public IP seems to be temporarily banned by our service provider as per the 429 Too Many Requests error message.

I use Express VPN connecting to the Washington DC datacenter. I switched to a datacenter in Europe and all is working again.

Yep, looks like your previously chosen outbound server is being used for scraping websites to collect data for AI training. These scrapers will send excessive requests (effectively a DoS attack) until the IP is blocked - either by CloudFlare or our hosting provider - and then switch to a different IP and round it goes. That's why nowadays you're more likely to get random intermittent network issues for this or that domain / server when connecting from a public shared IP that is also used by scrapers.
