Unable to synchronize via any device

Using Joplin on Windows 10 22H2:
Joplin 2.10.18 (prod, win32)
Client ID: 08acad8bc45f4879849c084aa9c85723
Sync Version: 3
Profile Version: 42
Keychain Supported: Yes
Revision: c67f5fa

I am currently unable to synchronize my notes on any device I am using: Laptop, iPhone, iPad. Usually happens with ease by tapping on "Synchronise". WiFi connection fine for every other PC/phone/ipad function (browser, email client, etc.).

This error message appears in Joplin side panel above "Synchronise" button:

Last error: Error: Error 502 Bad Gateway: 502 Bad Gateway

502 Bad Gateway

Whose gateway is the problem? Joplin's? What should I do?

I'm seeing the same problem. Looks like the Joplin Cloud server is down. Even going to https://joplincloud.com/ via a web browser shows the same error message:

502 Bad Gateway
nginx/1.18.0 (Ubuntu)

OK. Problem just went away. Anyone know the cause or location?

Hello, sorry for the trouble, Joplin Cloud was down for maintenance for a short time, but it should work again now. Please try synchronising again and let me know if you notice any other issue.

Thank you for the timely update.

Love this program.
