Scheduling Software Keeps Disconnecting — Why It Happens & How to Fix It
Quick Answer
Scheduling software keeps disconnecting because of one of three root causes:
- Auth token expiry — OAuth tokens expire and the software loses permission to your calendar or third-party service. Fix: re-authorize the connection in your integration settings.
- API rate limits — too many sync requests hitting the vendor's API, causing the connection to be throttled or dropped. Fix: increase sync intervals or upgrade your plan tier.
- Webhook misconfiguration — the receiving URL changed, SSL expired, or the endpoint stopped responding. Fix: check the webhook URL is still live and returning 200.
Which one is it? Check in this order
- Go to your integration settings — look for a "re-authorize" or "reconnect" button. If it's there and lit up, that's cause #1.
- Check your sync logs for "rate limit" or "429" errors. That's cause #2.
- Test your webhook endpoint directly — paste the URL in a browser or curl it. If it's unreachable, that's cause #3.
- Is the problem intermittent or constant? Intermittent = usually rate limits. Constant = usually auth or webhook URL.
When to escalate
- You've re-authorized three times and it keeps dropping — that's a deeper OAuth config issue
- The problem is costing you missed bookings or customer no-shows per week
- A vendor quoted you $500+ and you're not sure if it's necessary
- You've spent more than 90 minutes on it without a clear diagnosis
Dealing with this right now?
Scheduling software disconnections are almost always OAuth token expiry or a webhook endpoint that stopped responding after a server restart. Here is the fastest way to confirm which one is your issue.

Why is my scheduling software not working or crashing? +
Scheduling software failures in 2026: (1) Calendar sync broken — Google Calendar or Outlook OAuth token expired. Reconnect in your scheduling tool's integrations settings. (2) Booking page not loading — often a DNS or CDN issue with the scheduling tool's hosted page. Try a hard refresh or check the tool's status page. (3) Availability not updating correctly — timezone mismatch between your calendar and the scheduling tool; verify both use the same timezone. (4) Email confirmations not sending — SMTP or email provider misconfigured; check spam folder and email settings.
How do I fix scheduling software that keeps disconnecting from my calendar? +
Calendar disconnect fixes: (1) For Google Calendar: go to your scheduling tool's integrations, disconnect and reconnect Google Calendar. You may need to re-grant all permissions. (2) For Outlook/Microsoft 365: corporate IT policies sometimes revoke third-party app access; check with your IT team or reconnect via an admin account. (3) For Calendly, Acuity, or Cal.com: token expiry is the most common cause — these tools need periodic re-authorization. (4) Check if you changed your Google/Microsoft password recently — password changes revoke all OAuth tokens.

How do I troubleshoot scheduling software step by step? +
Scheduling software diagnosis: (1) Test a booking yourself from a fresh browser session to see the exact error. (2) Check your calendar for conflicts — overlapping events block availability. (3) Verify timezone settings in both your scheduling tool and your calendar app. (4) Check the booking flow end-to-end: availability shows → slot selectable → confirmation email received. (5) Check your email deliverability — confirmation emails often land in spam. (6) Contact the scheduling tool's support with a screenshot of the error — most respond within 4 hours.
