Seeing this error? Case-sensitivity, an expired captcha, or browser cache issues are the usual reasons. Below are the common causes and the fixes that resolve it for most users.
Why this happens
- The captcha is case-sensitive and you typed it in the wrong case.
- The captcha expired because the page was open too long.
- Cached or corrupted browser files are showing a stale captcha image.
- An ad-blocker or script blocker is stopping the captcha image from refreshing.
How to fix it
1
Refresh the captcha
Click the small refresh icon next to the captcha to load a fresh code before typing.
2
Match the case exactly
Type letters in the exact upper/lower case shown. The portal captcha is case-sensitive.
3
Clear cache or use Incognito
Open the portal in a private window, or clear browser cache and reload.
4
Disable blockers
Turn off ad/script blockers for the portal, which can interfere with the captcha refresh.
Important
If the problem is on the portal side (maintenance or server load), no browser fix will help — confirm with a second network first.
