429 rate limit error July 2026

[puderquaste132]

Hi everyone, I'm getting since yesterday constant 429 rate limit errors on mobile login strategies when trying to authenticate:

mobile+cffi returned 429: Mobile login returned 429 — IP rate limited by Garmin
mobile+requests returned 429: Mobile login returned 429 — IP rate limited by Garmin

Is there a workaround or recommended way to bypass this IP rate-limiting block? I was using it for 2 weeks without any problems and suddenly it stopped working. I tried to create a new login token, but if fails everytime.

Hit this exact failure in early July on my daily Garmin sync, same message from both mobile strategies. In my case Garmin was not blocking the account; it was rate-limiting login attempts from my IP, and the cause was self-inflicted. My scheduled job called client.login() with no tokenstore, so every single pull did a full SSO login. One scheduled pull plus one manual run in the same morning was enough to trip it, and it kept 429ing for days because the job attempted a fresh login every morning.

The fix was not working around the limit, it was to stop logging in. Log in once, persist the token store, and resume it on every later run:

client = Garmin(email, password)
client.login("~/.garminconnect")  # resumes the saved session when present;
                                  # only does a full SSO login when missing/expired

Setting the GARMINTOKENS env var to the same path works too.

Two practical notes from that episode:

1. While your IP is inside the limit window, every retry counts as another login attempt, and "create a new login token" is also a login attempt. Stop retrying for several hours first, then do one interactive login to seed the token file.
2. Once the token file exists, later runs do not touch the SSO endpoint at all. My job has run daily for over three weeks since the change with zero 429s.

Worth checking how many logins per day your setup was actually doing.

mobile+cffi returned 429: Mobile login returned 429 — IP rate limited by Garmin
mobile+requests returned 429: Mobile login returned 429 — IP rate limited by Garmin

This is normal, we go through a list of strategies, these first two almost always fail, it's just wa warning.

The next ones in the list are the better ones and should just work, make sure you save the tokens, and use them, don't login with login/passwored every time.
