Webhook url does not receive any post sometimes

Question

using Messaging API with webhook
webhook api sometimes cant get message since 2021/08/15
it works correctly before 08/15

i try to verify webhook, but it comes to "An error occurred when sending the webhook event object" sometimes, not always
**sometimes** it virify Success.

when virify comes to error , my webhook api didnt get any request from line server.
i check my SSL certification, and it is valid from 08/Jul/2020 to 25/Aug/2021, Issuer	DigiCert SHA2 Secure Server CA
any thing can i do for this problem?

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

I add Google Load Balancer behind my server temporary，and everything works fine.
I think it maybe network issue between gcp taiwan & line.
