Hello, in several requests I received the error message below, what causes this and how to fix it?

503 Service Unavailable

No server is available to handle this request.

that is for web3api calls?

Our prod application is also down. I am getting CORS errors in the console log.
Didn’t update anything so I think its from Moralis side.

Would be good to have no Friday-deploy rule :wink:


after server restart it started to work.

Seeing the same thing. Server came back after a restart, but no events were synced while it was down, so the data for the dapp is all broken

can you check again after 10-20 minutes after the server restarted? or it already passed that time

It already passed that time. Restarted more than an hour ago

what is the server subdomain/url?


I see that new events are synced now in some tables, what events are exactly missing?

There’s a 4 hour gap between 11:00-ish utc and 15:00-ish utc (not exact, but you’ll see it). Guessing the events were sent to the server while it was borked so it didn’t process them and didn’t re-ask for them.

But… if this had been a smaller outage, I might not easily be able to check, so ideally you have a way to find and fix gaps aitomatically.

can you send me a DM in discord?
