Custom domain on container apps gives ERR_CONNECTION_RESET error

Question

Hi, I am fighting this second day and run out of ideas.

I have creates Azure Container Application and wanted to provide my custom domain for it. So I bought a domain at domain registrator, changed DNS records and stuck. The result is that when I go at: http://sevigo.eu (without SSL) it gives me 404 error. If I go through SSL: https://sevigo.eu it gives me ERR_CONNECTION_RESET.

What I've done is:

• create Let's Encrypt certificate in my registrator for domains: mail.sevigo.eu, sevigo.eu and www.sevigo.eu
• paste certificate key and certificate itself into pem file like: -----BEGIN CERTIFICATE-----
  cert content
  -----END CERTIFICATE-----
  -----BEGIN EC PRIVATE KEY-----
  key content
  -----END EC PRIVATE KEY-----
• changed DNS A record sevigo.eu. to ip provided by Azure
• added DNS TXT record with name asuid and content provided by Azure

Next

• go to my container app in azure
• go to Custom Domains
• Add custom domain
• type domain name: sevigo.eu and import PEM file that was created earlier.

All the validation passed, everything looks ok to me:

but now when I try to ping sevigo.eu all I get is time out. But ping shows valid IP address.
When I type https://sevigo.eu from browser (InPrivate) I get ERR_CONNECTION_RESET. When I try to call it from Postman - the same: ECONNRESET

This is what my DNS records look like:

I really don't know what can I do more... My domain registrator says that it should be something on Azure site.
What can be important, if I type IP given from Azure to my browser: 20.67.141.16 I am also getting "Connection reset" error. But when I type original address: https://sevigo.purpleisland-63e8604e.northeurope.azurecontainerapps.io I am getting the real site.
