Certificates orders are failing with 500 error on Staging

Hello team,

We are experiencing today continues errors trying to order certificates with this error:

"acme: error: 500 :: urn:ietf:params:acme:error:serverInternal :: During secondary validation: Remote PerformValidation RPC failed"

Domains are managed in Cloudflare. We use the Lego ACME client.

Update,
Issue seems to auto resolved when using LE prod account. Still seeing such errors when using LE staging account.

Any update on this?
The --staging seems to not work, but it works for a prod account (@ArikS thanks for the update). However, my ask is to make it work for staging setup as well, due to rate limit.

Just tried on prod account, it works for me. I lost a lot of time debugging stage account (does not work currently for me) last two days. Stage seems not to work.

Had the same error as well with the staging environment, and no problem in the production environment.

I can confirm we are hitting this too on Stage failing all the certificate requests

same problem, staging fails. Also for several others, see link

@lestaff staging failures seem to be occurring everywhere right now #2

This is now fixed!
