If your Odoo free trial has been rejected even without using proxy or ad blockers, it could be due to several reasons unrelated to these settings. Odoo might automatically reject trial requests from the same user if an email address or IP address has previously been associated with a trial, even if that trial was used a long time ago. Additionally, sometimes if the trial was activated on a particular device or network, it may affect eligibility for another trial on that same setup.

Here are a few actions you can try:

1. Clear Browser Data: Clear cookies and cache or try a different browser.
2. Switch to a Different Network: Sometimes, changing your network (such as from Wi-Fi to a mobile hotspot) may help.
3. Contact Support: If none of the above works, contacting Odoo support may provide additional assistance, especially if your trial access is needed for a specific purpose like training or evaluation.

If the trial remains unavailable, you could consider Odoo’s demo or sandbox environments as alternatives. Odoo also has a Runbot for testing purposes. For more support, you can also reach out directly through Odoo’s contact page or support team.
