If you see a temporary error in Gmail, it usually means something small is interrupting the service. Common reasons include heavy server traffic, old browser cache, problem-causing extensions, or a weak internet connection. Often, the error goes away on its own, but you can try fixing it by clearing your cache and cookies, turning off extensions, using a different browser, or checking your internet speed. Keeping your browser updated and avoiding suspicious third-party apps can reduce the chances of it happening again. If it still doesn’t work after hours, reach out to Gmail Support.
