Just after 62 version update I'm getting this trouble (screenshot)

localhost:8171 uses an invalid security certificate. The certificate is not trusted because it is self-signed. Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT


Chrome and event Edge work fine with this host

Any reason for this?

Thanks for the answer, but no, router has nothing to do with it. It's a local host which is created by the local software https://qz.io/ with custom certificates https://prnt.sc/krncp1 Besides this problem happens not only my computer but a lot of our remote staff experience it just after 62 update
