Looks like the errors occurred at the proconnect.intuit.com server which happens sometimes, I understand that it is very hard to control every error, so I would like to suggest a tool that can help fix all the website errors very quickly. I am speaking about the https://linko.app/. I used it for all my websites and it is a very useful thing, it checks your website for errors 24/7 and reports if something is wrong so you can fix it very rapidly.
