Mobile apps and the website often run on different infrastructure. If Microsoft 365 fails in the app but works at m365.cloud.microsoft in a browser, an app update or a cache clear inside the app usually resolves it.
Open any other site. If nothing loads, the issue is your network rather than Microsoft 365. On Windows run ping m365.cloud.microsoft and nslookup m365.cloud.microsoft in Command Prompt; on macOS or Linux use Terminal. A DNS failure and a server failure look identical in a browser but are very different problems.
Load m365.cloud.microsoft in a private or incognito window. If it works there, clear cookies and site data for m365.cloud.microsoft in your normal browser rather than clearing everything.
Switch from Wi-Fi to mobile data, or vice versa. Regional ISP routing problems are common and often affect one carrier while others are unaffected.
