Hello. Thanks for yours services first of all but i have a problem with my site (vresekdiloseis.gr) … when i check/run fron mobile phone… redirect it(??) to another web site at this → https://www.pelagoszante.gr/.
There seemingly is a redirect for (presumably) mobile user agents, however it does not redirect to the domain you mentioned but rather to ftp.vresekdiloseis.gr.
As to why, that will be something in your server configuration and this is where you will need to look. Unfortunately this is not related to Cloudflare, so the question is a bit off-topic here. It will be best to take it to e.g. StackExchange.
