Welcome to the Microsoft Q&A forum.
We understand that you're encountering a frustrating issue with accessing the Azure sandbox.
Since you mentioned that you’ve used one of your ten available sandboxes for the day, it’s essential to ensure that you still have access to a sandbox. If all ten are used, you may need to wait until the next day when they reset.
Here are some additional steps you could consider troubleshooting this problem:
- Sometimes, refreshing the browser can resolve temporary glitches.
- Logging out of your Microsoft Learn account and then logging back in may help resolve any session-related issues.
- You might want to try accessing the sandbox in an incognito / private browsing window to bypass potential cookie / caching issues.
- Please consider disabling any browser extensions / add-ons that could interfere with page loading.
- If possible, trying a different network could rule out any network-related issues.
- Ensuring that your browser is up-to-date can help, as older versions sometimes experience compatibility issues.
Should you encounter any issues, please do not hesitate to contact us, and we will be pleased to assist you further.
