I add Google Load Balancer behind my server temporary，and everything works fine. I think it maybe network issue between gcp taiwan & line.
Yep, my server is GCP Asia-east1-b
this happened frequently recently. even the webhook verify button got error quite often.
i am using AWS in eu zone btw.
my server is on GCP too it works normally now, and i didnt do anything. verify success always right now , maybe something have been fixed.
I try to create a Google Load Balancer, but it's still can't work, I think the ip is same with asia-east1-b so I used proxy to let my webhook can receive hope line can solve this problem...
Thank Far, good luck
