Hey @xetrov05, It would be interesting to know what IP address is being returned from that function and why it’s not being flagged as internal by the function if the API that you’re connecting to sees it as internal.
All of that said, if you need a single, relatively static IP address you’re not going to get that in Glitch’s environment. We host our servers in AWS’s US-East-1 region, but your project can be hosted on any IP address in those ranges, which means it can be one of millions of possible IP addresses. You can use the snippet I provided in What IPs must I whitelist so my Glitch project can access my MongoDB database? to be able to see what the possible ranges might be, but I’m not sure that’s going to be helpful for you.
Sorry for the inconvenience!
