Hi, guys… I generated my valid certificate ([https://www.sslforfree.com](https://www.sslforfree.com)) to my keycloak, however I am not able to install it in any way. I’m using the image of the docker. 1- I’ve renamed it to tls.crt (root) and tls.key (private) 2- I already put the two files inside certs 3- I already put it inside / etc / x509 / But it doesn’t work, can you help me? ---

> [@guilhermeasgrj](#): > > Client requested protocol TLSv1 is not enabled or supported in server context Hi. I don’t use docker but this problem is generated by Wildfly. The client require TLSv1 but Wildfly reject it as insecure. In wildfly’s standalone search for the https-listener and change enable-http2 ``` ``` i don’t remember if the parameter must be true or false (try to change it). Pay attention to certificates. From middle 2019 (I don’t remember the exact month) some policies in SSL certification are changed and browser starts to reject some certificates or marking it as insecure.
