No ingress for a few satellite, error service ping satellite failed

I found no ingress for a few satellites, e.g. ap1, eu1, saltlake. but other satellites are ok, e.g. us1, us2.

I search the log and found can’t dial the following 4 IP+port,
Fail to dial 34.88.199.144:7777, 34.102.123.130:7777, 34.141.33.112:7777, 34.92.229.119:7777
Is it normal? anyone else face the same issue?

Here’s the logs

Resolved, these IPs are from old DNS record, not sure why, after restarting router it works.
