I’m using the ERPNext hosted version. The home page, https://diago.erpnext.com/ has said this for the past few days:
**Sorry! **
We will be back soon.
Don’t panic. It’s not you, it’s us.
Most likely, our engineers are updating the code, and it should take a minute for the new code to load into memory.
Try refreshing after a minute or two.
What could the problem be?
I think, you’re putting incorrect URL. I can access own ERPNext hosted.
As far as I know, the URL I posted is correct. Do you have some evidence or reason to think that it is incorrect?
Try with any wrong url. You’ll encounter same error as you mentioned. i.e. why Guessing. Might be also putting wrong URL.
@James_Kitchen try cleaning browser cache and run bench clear-cache from frappe-bench folder
