Please don’t use AI to fluff up your post. Just provide the information we need to help you in a clear an concise way. Having us scroll through AI junk doesn’t help anyone. Just saying something like “my site artigram.rf.gd is showing a 403 forbidden error and I don’t know why, please help” is just as informative as the article you’ve shared here.
As for the issue itself, the original account of both artigram.rf.gd and flik.rf.gd is on hosting volume vol7_6, which is currently being migrated to a new server. Your files are currently still stuck in transit, which is why your website files are not accessible right now, and why flik.rf.gd is returning a 403 error.
Your website files will be copied soon, and when they are, your website flik.rf.gd will start working again.
For artigram.rf.gd, you appear to have removed the domain from the old account, added it to a new account, and deleted the htdocs directory. Because the htdocs folder is missing, you see a 404 error.
Your original website files are still in transit and will be available on your old account soon. However, because you’ve been moving your domain, it’s up to you to make sure that the websites files are moved to the right account and directory so they will be active on your domain again.
