Site in Vercel problems with external loan service

Hello community, and thank you for this space. I recently published a website on Vercel belonging to a client. I’m having an issue with an external system called LOAN that they use to submit the digital signature form for loans. I need help because I don’t understand the problem.

They sent me a message stating it was a hosting/infrastructure provider issue, but I can’t resolve it.

Should I request an IP address or DNS from them?

Thank you.

Hi @florenciaparodi, welcome to the Vercel Community!

I’m not sure if this could be related to Vercel. Can you explain a bit more about what the LOAN system does and why Vercel isn’t working for them?
