Return to Travelchain and retry the provider button after checking whether the browser blocked the new tab or redirect.
What to know
The redirect uses an allowlisted HTTPS destination and a stored click ID. A disabled partner, expired click, content blocker, network error, or popup rule can stop it.
What to do
- Allow the new tab for Travelchain.
- Check the address bar or blocked-popup notice.
- Disable only the relevant blocker rule if safe.
- Run the search again and choose the provider.
