Routing between Cloud Front Servers and Argo Tunnel not working

Hello, I have argo tunnel setup since 4 days ago. I have Firewall rules implemented by source IP to CNAME www.synackrstnull.net that redirect to Argo Tunnel ssh. Sudently this afternoon the server stoped to answer. I asked the server provider to perform a reset. The Argo Tunnel came up but I still cant access the machine. I can’t even see hits on Firewall overview rules allowed or denied to CNAME www.synackrstnull.net. I suspect its a internal routing problem between Cloudflare Front proxys and Argo Tunnel. Can you please check? Kind regards Ali
