Problem with Issue the SSL by Let's Encrypt

In my server Let's Encrypt issue the SSL Cert often have the error like below:

Could not issue an SSL/TLS certificate for seagullmodels.com
Details
Could not issue a Let's Encrypt SSL/TLS certificate for seagullmodels.com. Authorization for the domain failed.

Details
Invalid response from https://acme-v02.api.letsencrypt.org/acme/authz-v3/135884297466.

Details:

Type: urn:ietf:params:acme:error:connection

Status: 400

Detail: During secondary validation: 103.131.74.34: Fetching http://seagullmodels.com/.well-known/acme-challenge/SItq48MB_BFmYpI5KDMLJ879GIZwDeN3UpTeu5Koz_4: Timeout during connect (likely firewall problem)

I already checked the link verify is working around the world , the link http://seagullmodels.com/.well-known/acme-challenge/SItq48MB_BFmYpI5KDMLJ879GIZwDeN3UpTeu5Koz_4

even I checked the log access in my server, have a record access by let's encrypt with status 200.

here is the log access in my server:

2022-07-29 07:11:12 103.131.74.34 GET /.well-known/acme-challenge/SItq48MB_BFmYpI5KDMLJ879GIZwDeN3UpTeu5Koz_4 X-ARR-CACHE-HIT=0&X-ARR-LOG-ID=3c7ecff0-81ba-4131-8242-dc8a664c1612&SERVER-STATUS=200 80 - 23.178.112.208 HTTP/1.1 Mozilla/5.0+(compatible;+Let's+Encrypt+validation+server;++https://www.letsencrypt.org) - acme-challenge.localhost 200 0 0 501 269 617

I don't know why the verify link had been access by let encrypt but It can not issue the cert and raise the error timeout.

We perform validation from multiple locations. It looks like it succeeded from one location, but none of the others were able to connect. Do you have some sort of firewall that's blocking some IP addresses?
