I think. In the domain menu, I clicked on make default, I thought it just changed the yunohost access domain. (to the sso page, admin page etc)
I have 3 domain link to that install
domain0.tld, domain1.tld and domain3.tld
right now, I access to yunohost via domain0.tld, but I want to use it for other purpose, so I made default sub.domain0.tld
"portal_domain": "sub.domain0.tld",
"portal_path": "/yunohost/sso/",
"redirected_regex": {
"sub.domain0.tld/yunohost[\\/]?$": "https://sub.domain0.tld/yunohost/sso/"
},
If I set the default to domain0.tld everything work normally again, I can login etc
