Strava and Intervals
Check Intervals.icu key or connection
Intervals.icu may require correct credentials or API key. If they change or expire, synchronization may fail.
Recommended steps
- Check the configured user and key.
- Review that Intervals.icu accepts the activity.
- Try with a recent and complete activity.
- If only one activity fails, it may be the file.
- Update the key if you have changed it.
- If in doubt, share the exact error without posting private data.
