Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Please check if you are using a Firewall, as it may prevent saving the changes.
If you are using a Firewall, please whitelist this route:
/wp-json/rankmath/v1/updateMeta
Whitelisting the route should fix the issue.
You can check this link for more information:

I hope this helps. Looking forward to helping you.
This was helpful, but one thing I’d add when answering this question next time is that the firewall on the webhosting server not the local browser firewall settings. 🙂
