Email routing errors

Hi, it seems I have things working however while setting up and adding several “Custom addresses” I received different errors. These were red banners that went across the entire bottom of my browser. The first error said (Code: 2002) which happen a few times then I left the page and came back to try to add more custom addresses and received another error saying “API Request Failed: POST /api/v4/accounts/724e3dfb7f…/intel/attack-surface-report/checkers/spf_check (502)”.

At first I was thinking the “Custom addresses” had a limit but as mentioned above it eventually took all the addresses (7 total). Is there a limit???

Thank you.
