When I click on Help -> Check for Updates ... the new window pops up and the cursor spins for a bit and I get the message "information about the latest version of FileZilla could not be retrieved. Please try again later." and a try again link is shown. No matter when or how many times I try this is all that I get. I do not have a proxy in the way. Anyone have an idea of what is wrong? Should I file a bug ticket? Client info below.

Cannot reproduce. Make sure FileZilla is not being blocked by some firewall or AV product.

May I get the target URL? I would like to try telnet and nc to get back any errors that may help debug my connectivity.

Checking for updates is done through update.filezilla-project.org port 443

Looks like the certificate is self-signed. I do not have that cached nor would I want to if it is at all possible to avoid it. Are you able to use a free LetsEncrypt certificate?

Why? It is not a public service and only FileZilla products will use it.

Apart from that, and contrary to what the CA trust mafia wants you to believe, self-signed certificates are not less safe as the paid ones. As long as you have verified or do trust the issuer/signer, they are perfectly safe. update.filezilla-project uses a self-signed certificate, and FileZilla knows (and trusts) it. I see no problem in that.

By the way, FileZilla itself does not make any distinction between self-signed certificates and paid ones. Each and every certificate not known to FileZilla needs to be confirmed by the user. There is no implied trust at all.

The certificate on update.filezilla-project.org is not self-signed. It is signed by the updater CA trusted by FileZilla, in fact the only CA FileZilla trusts for updates.

But you didn't pay a CA to sign it.

Correct. For security reasons I created my own CA, one that cannot be compromised by the highest bidder or the government.

That was what I meant. Maybe should have said "self-issued", not self-signed.
