ERPNEXT on AWS Amazon site can’t be reached

I made install for ERPNext on AWS Amazon, and I began to use it, Just me ( one user ).
But when I make many change in ERPNext setting suddenly show :

site can’t be reached
took too long to respond.

I have to wait about 10 min then I make refresh to open.
Or I have to made restart for my modem .

How to solve this problem, Plz ?

Hi thecoder, from what you have described, I suspect it might not be an issue in ERP.
More like either your internet connnect is bad or your IP address has been banned by AWS.

I would suggest you refer to the group access rule set up in AWS. All my guesses though.

Probably fail2ban banned your IP.

But when I make restart for my modem it is work directly .

Also site1.local still same as it in file nginx.conf
