Hi @marioVP,
It appears the IP addresses are passing on end. Would you confirm if you're still getting errors? I'm trying to determine if this is temporary.

Hi @Gordon-C
The problems usually start at midnight PST. We have detected this pattern in the last 4 or 5 days. At the moment it seems to be working fine, but as I said before, problem starts around midnight

When the problem starts at midnight, how long do you receive the errors before the problem corrects itself?
