Good day fellow Developers! I recently installed open edx tutor on a fresh instance. I followed the instructions on the open edx tutor documentation and everything seems to be working fine. But there seems to be a problem with the tutor-MFE plugin. There are times that it works, and there are times that it don’t. For example, if I would click the “Profile” or “Account” tab here: ![image](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/1/1b1f2a1f19266b98e5f1498028a33da9d74bfaa6.png) It would redirect me to the MFE\_HOST. But on my end, there are times that it displays what is to be expected, but most of the time it crashes like this: ![image](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/9/99ef300085d1d9ee29eb1fe1ccf7b8b56e2a1109.png) I just simply followed the directions in installing tutor and by default, mfe is installed. I disable it for quite some time, but when I visit the “Profile” or “Account” tab again, it crashes the same way like this: ![image](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/2/2e2bafbb823dd9370d0a5cb1a0eb93ff6513d399.png) Can anyone please help me? I’m pretty sure this discussion will help others as well. Thank you! ---

It’s hard to know the issue without looking at the logs, both the browser based logs (developer console) and tutor logs i.e. (`tutor local logs --tail 10 -f`) and then duplicate the bug. ---

**UPDATE:** After using > tutor local logs --tail 10 -f The log file says something like this: `lms_1 | 2022-08-20 12:18:26,428 INFO 7 [tracking] [user 4] [ip 112.207.109.56] logger.py:41 - {"name": "/account/settings", "context": {"user_id": 4, "path": "/account/settings", "course_id": "", "org_id": "", "enterprise_uuid": ""}, "username": "Engr_James", "session": "9244d954c2c9453d243975b84a5baf17", "ip": "112.207.109.56", "agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.5112.81 Safari/537.36 Edg/104.0.1293.54", "host": "test.tmtg-clone.click", "referer": "https://test.tmtg-clone.click/dashboard", "accept_language": "en-US,en;q=0.9", "event": "{\"GET\": {}, \"POST\": {}}", "time": "2022-08-20T12:18:26.427892+00:00", "event_type": "/account/settings", "event_source": "server", "page": null}` `lms_1 | 2022-08-20 12:18:26,433 INFO 7 [openedx.core.djangoapps.cors_csrf.helpers] [user 4] [ip 112.207.109.56] helpers.py:64 - Origin 'https://test.tmtg-clone.click' was not in `CORS\_ORIGIN\_WHITELIST`; full referer was 'https://test.tmtg-clone.click/dashboard' and requested host was 'test.tmtg-clone.click'; CORS_ORIGIN_ALLOW_ALL=False` `caddy_1 | {"level":"info","ts":1660997906.4398189,"logger":"http.log.access.log0","msg":"handled request","request":{"remote_addr":"112.207.109.56:14868","proto":"HTTP/2.0","method":"GET","host":"test.tmtg-clone.click","uri":"/account/settings","tls":{"resumed":false,"version":772,"cipher_suite":4865,"proto":"h2","proto_mutual":true,"server_name":"test.tmtg-clone.click"}},"user_id":"","duration":0.025716977,"size":0,"status":302}` `lms_1 | [pid: 7|app: 0|req: 7/17] 172.18.0.11 () {58 vars in 4427 bytes} [Sat Aug 20 12:18:26 2022] GET /account/settings => generated 0 bytes in 25 msecs (HTTP/1.1 302) 7 headers in 357 bytes (1 switches on core 0)` `lms_1 | [pid: 19|app: 0|req: 8/18] 172.18.0.11 () {58 vars in 4324 bytes} [Sat Aug 20 12:18:27 2022] POST /login_refresh => generated 213 bytes in 110 msecs (HTTP/1.1 200) 10 headers in 1691 bytes (1 switches on core 0)` `caddy_1 | {"level":"info","ts":1660997907.931983,"logger":"http.log.access.log0","msg":"handled request","request":{"remote_addr":"112.207.109.56:14868","proto":"HTTP/2.0","method":"POST","host":"test.tmtg-clone.click","uri":"/login_refresh","tls":{"resumed":false,"version":772,"cipher_suite":4865,"proto":"h2","proto_mutual":true,"server_name":"test.tmtg-clone.click"}},"user_id":"","duration":0.111898831,"size":213,"status":200}` > And here is the BROWSER Error ![image](https://us1.discourse-cdn.com/flex020/uploads/openedx/original/2X/0/028fbaf14ddb9af57fde94aac6a14b69ec875b87.png) ---

**UPDATE** For all my credentials, I am using subdomains. For example: My LMS\_HOST is `test.domainexample.click` while my CMS\_HOST is `studiotest.domainexample.click` and my MFE\_HOST is `appstest.domainexample.click` Does that have an effect on this? Because on the other hand, when I tried using the created domain directly, such as for example: My LMS\_HOST is `domainexample.click` while my CMS\_HOST is `studio.domainexample.click` and my MFE\_HOST is `apps.domainexample.click` everything seems to be working fine. Now, my follow up question is this: If it does have an effect, is there a way where I can still use the same subdomains such as the `appstest.domainexample.click` but still make the MFE\_HOST work? ---

How about [apps.test.example.com](http://apps.test.example.com)? You can have your site on [example.com](http://example.com) LMS on [test.example.com](http://test.example.com) Everything else on \*.test.example.com There might be other possible solution to add all subdomins to cors whitelist but i am not sure how well that works. ---

Tried this as well. But it is not possible. I also tried adding them to cors\_whitelist but it doesn’t seem to be working. ---

To resolve the issue for me when I had, I changed the cookie domain for use case make sure the cookie domain is “. domainexample.click.” I think that value is lms.env.yml it should be `SESSION_COOKIE_DOMAIN: ". domainexample.click."` **Assuming MFE\_HOST is not subdomain of LMS** ---

I too was trying to make the MFE host be a subdomain of the base domain rather than like it is defined here [tutor-mfe/plugin.py at master · overhangio/tutor-mfe · GitHub](https://github.com/overhangio/tutor-mfe/blob/master/tutormfe/plugin.py#L13). @regis Is there a way to configure the MFE\_HOST to be located at a subdomain other than the LMS\_HOST? I keep getting this error when viewing the MFE host. No container logs or browser logs seem to give us any clue what’s wrong. **An unexpected error occurred.

So I was able to get the MFE to load with the following configuration settings. I didn’t have the `{cms|lms}-env` tutor patches overridden and that was the issue. As @ghassan mentions [here](https://discuss.openedx.org/t/tutor-mfe-plugin-fresh-startup-error/8104/7) I used the `.{{ BASE_DOMAIN}}` for the SESSION\_COOKIE\_DOMAIN value along with the same SESSION\_COOKIE\_NAME to allow the session to work across both the CMS and LMS applications. ```auto "BASE_DOMAIN": "example.com" ``` Tutor Plugin Patches `cms-env` `lms-env` ```auto "SESSION_COOKIE_DOMAIN": ".{{ BASE_DOMAIN }}", ``` `openedx-cms-production-settings` `openedx-lms-production-settings` ```auto SESSION_COOKIE_DOMAIN = ".{{ BASE_DOMAIN }}" SESSION_COOKIE_NAME = "sessionid-" ```
