Plugin (suddenly) has a problem logging in to the API

[johannfenech]

What issue do you have? Noticed that the meross plugs (mostly MSS210 and 310) are not working in homebridge. The plugs show in the accesories list, but cannot be controlled. They work well from the native meross app, so not a connectivity issue.

Details of your setup.

• Do you use (1) Homebridge UI-X (2) Homebridge CLI or (3) HOOBS?
  HomebridgeUI-X (running native on Ubuntu 22.04.3 LTS - on Intel i3)

• Which version of Homebridge/HOOBS do you have?
  Homebridge v1.7.0 · UI v4.55.1

• Which platform do you run Homebridge/HOOBS on (e.g. Raspberry Pi/Windows/HOOBS Box)? Please also mention your version of Node.js/NPM if known.
  Ubuntu 22.04.3 LTS / Node.js v18.19.0

• Which version of this plugin (homebridge-meross) do you have? Has the issue started since upgrading from a previous version?

10.3.0 - No, the issue started yesterday, and I am not aware of any updates (unless there were some ubuntu unattended upgrades I do not know of)

• Which Meross devices do you have that are causing issues? Please include product models if applicable.
  All meross items (mostly Plugs MSS210 and 310) but the issue seems to be with the login

Please paste any relevant logs below.

[2/6/2024, 8:01:15 AM] [Meross] Disabling cloud client as access token is invalid - check your credentials in the plugin config at default.getDevices (file:///var/lib/homebridge/node_modules/homebridge-meross/lib/connection/http.js:227:17).
[2/6/2024, 8:01:15 AM] [Meross] ***** Disabling plugin. *****
[2/6/2024, 8:01:15 AM] [Meross] ***** Neither of username and password nor user key has been configured, or there was an issue obtaining cloud devices. *****

The account has 2FA enabled, and works well on the native app (Used to work in the plugin too until yesterday at some point). I have changed the password just in case, to no avail.

Since it seems no one else is having this issue, would not exclude some issue on my end. The Homebridge also has other plugins for other brands installed, and they are able to communicate with their respective api's.

Please let me know if any more info is required, and above all thank you.

For what its worth, I have disabled 2FA on my account, and it now seems to work

I had the same issue and disabling 2FA also worked. Seems to be an issue w 2FA specifically.

[RateThePaladin]

Same problem here - disabling 2FA did fix the issue, but I would much prefer to have it enabled for security purposes

[designgears]

Probably the same issue, but I didn't have 2fa enabled, but enabling and disabling it fixed it.
