Orbi router is blocking me from accessing my personal website only?

[diabloooo1]

Hi all, I am having a very strange issue today, I have a personal website was playing some ssh login and all of sudden I found I can not access my website (says timeout), at first I thought it is the website issue, but later I found that I can access the website fine through phone 5G without wifi! This is very strange, I made sure there is no blocked website or whatsoever in the settings, but still the router seems only blocking my person website! All other websites are working fine!

Can someone please help? I think it must be related to my ssh testing somehow but I dont know what has happened...

Thank you!

Have you tried a different dns? 

Try a different DNS Server. Here's a few for ipv4. Also remember to change the ipv6 dns server if ipv6 is enabled
CloudFlare 1.1.1.1 and 1.0.0.1
GoogleDNS 8.8.8.8 and 8.8.4.4
