Fix Error 503 when logging in
Overview
How do I resolve a 503 error when trying to log in?
A 503 error can appear during login if your activity is mistakenly flagged by CxPlanner’s security filters. This is uncommon, but certain browser tools may block or alter login requests.
When and why to use this
A 503 error usually appears when:
- Your login attempt is flagged as unusual by security filters
- Browser extensions interfere with the login request
- Password managers or ad blockers block CxPlanner’s scripts
The system does not allow login until the interfering factor is removed.
How to - step by step
- Switch browser
Try logging in from a different browser (e.g., Chrome, Firefox, Edge).
- Disable interfering tools
- Temporarily turn off your password manager.
- Disable any ad blockers you may be using.
- Retry login
- Go back to [CxPlanner login]() and attempt to sign in again.
If the error continues after these steps, contact CxPlanner Support for assistance.
Behavior and results
- The error is not related to incorrect credentials - it is triggered by blocked or altered requests.
- Once the interfering tool is disabled, login proceeds normally.
- The issue is rare and only affects a small number of users.
