Do we know which version of mev-boost is it?

From @metachris: there was a rate limit validator registration calls / 5 min / IP We've increased it.

I'll ask the operator to try again.

From the logs it looks like the status check is still done every 30s without using the -relay-check explicitly. Removing that argument from startup gets rid of the 403/503 errors on the status check, not sure how that works out. However, even on 1.3.2 I still see the 403/502 on the registerValidator method on 3 separate instances.

Which country are the requests originating from?

Hi @metachris the requests are originating from France

Sep 30 '22 10:09 danspina1

it look like cloudflare blocks the requests. are you still seeing 403s?

Yes, it looks like once every 6 minutes on a few instances, time="2022-10-06T15:50:47Z" level=debug msg=registerValidator method=registerValidator module=service time="2022-10-06T15:50:47Z" level=warning msg="error calling registerValidator on relay" error="HTTP error response: 403 / error code: 1020" method=registerValidator module=service numRegistrations=25 ua=Go-http-client/1.1 url="https://boost-relay.flashbots.net/eth/v1/builder/validators" time="2022-10-06T15:50:47Z" level=info msg="http: POST /eth/v1/builder/validators 502" duration=0.035003311 method=POST module=service path=/eth/v1/builder/validators status=502

It looks like Cloudflare thinks your IP reputation is bad: https://community.cloudflare.com/t/community-tip-access-was-denied-error-code-1020/66439

Now we'd need to look at your setup, and which outgoing IP's you're using. Perhaps try rotating the IP / using a different one?

should be resolved, at least haven't seen any recent reports.

please comment to reopen

We are still seeing intermittent 403 errors. Please consider removing bot protection from cloudflare; they're notoriously finicky and tend to come and go.
