Work from the outside in. Each step rules out a whole family of causes.
- Is it only you?
Try another network (your phone on mobile data) and a private window. If it works there, your own network or your address may be blocked; see 429, 444 or the browser check.
- Does the domain point to the server?
dig +short www.example.commust print the server's IPv4 address. A recent DNS change can take a while. - Is the server up?
Console, the server: status Ready and the Graphs tab still updating. If the console cannot reach the server, open an urgent ticket.
- Are the services running?
Overview, Services: nginx, the PHP version of the store, mariadb and redis must be active. Restart the one that is not.
- What does the error say?
A 502 or 504 (gateway errors), a 500 or a white page (500 errors), an SSL warning (SSL).
Mention what you saw and the time in your ticket. With the server's logs we usually find the cause in minutes.
Did this solve it? If not, tell us what you see and we look at your server.
