  • Hi,

    Thanks a lot for your query and we are so sorry about the trouble this must have caused.

    Can you please ask your web host to whitelist our IP so that your website is able to connect with our API?
    Rank Math's IP Address:

    It should work fine after that.

    Thank you.

    I hope you are fine.
    My technician saw that no IP is blocked.

    After that I bought a license of another plugin because I thought that it might be the cause of the malfunction.
    It did not worked again.
    After that I disabled all other plugins but no luck.
    With only this Plugin enabled I get error message 503.

    Please advise.

    Thank you very much.
    Best regards.
