Error from ip-api.comSolved

For every user joining I get the following error:
"[Welcomer] Request to http://ip-api.com/json/ for STEAMID was unsuccessful. Status code: 404"
How can I disable or fix that?

I found out, changing it to http://www.ip-api.com/json/ fixed it, so it has to be a dns issue on my side
