@TheLumberjack @curt I just followed the [video](https://youtu.be/ZPkOQbVEnW0) and got a big process, the only difference with the video is the zac that installed with docker, but when access the https://${ZITI\_BROWZER\_VHOST}:${ZITI\_BROWZER\_BOOTSTRAPPER\_LISTEN\_PORT}, i got response like this. ```auto ubuntu@ip-10-1-2-109:~$ curl https://brozac.rootwang.link:8446 OpenZiti BrowZer Bootstrapper ``` The url of response is ```auto https://brozac.rootwang.link:8446/browzer_error?browzer_error_data==%7B%22status%22:409,%22code%22:1014,%22title%22:%22OriginTrial%20subdomain%20mismatch%20for%20feature%20%5BWebAssemblyJSPromiseIntegration%5D%22,%22message%22:%22Expected%20origin%20%5B*.cloudziti.io%5D%20but%20is%20accessed%20from%20%5B*.rootwang.link%5D%22,%22myvar%22:%7B%22type%22:%22zbr%22%7D%7D ``` and decode it ```auto {"status":409,"code":1014,"title":"OriginTrial subdomain mismatch for feature [WebAssemblyJSPromiseIntegration]","message":"Expected origin [*.cloudziti.io] but is accessed from [*.rootwang.link]","myvar":{"type":"zbr"}} ``` ![image](https://global.discourse-cdn.com/free1/uploads/netfoundry/original/2X/7/793e762ea72e22851eec5c17a9ff78cac03515c4.png) and i looked this [url](https://openziti.discourse.group/t/browzer-setup-error-1014-origintrial-subdomain-mismatch/2481/2) and did clear site data, but not worked. Then i enable `JSPI`, but still did not work. ![image](https://global.discourse-cdn.com/free1/uploads/netfoundry/original/2X/b/b845e9266e91537a81c158a8422557d34ff239d1.png) ![image](https://global.discourse-cdn.com/free1/uploads/netfoundry/original/2X/b/bfc9e4b997da0aace1511d77ed7282ecefe9e145.png) Finally i set the `ZITI_BROWZER_RUNTIME_ORIGIN_TRIAL_TOKEN` variable and restarted browzer-bootstrapper with "sudo systemctl restart browzer-bootstrapper", but still not work. ![image](https://global.discourse-cdn.com/free1/uploads/netfoundry/original/2X/3/31fcd14178afc25ffd2e9886dfdd453f74295d64.png) which step i was wrong. thanks. --- _[View the full topic](https://openziti.discourse.group/t/encount-a-problem-when-install-browzer-with-docker/2623)._
