I'm guessing there are some SSL certificates involved? If so, this issue is mentioned in the release notes: certificates that use e.g. SHA1 as the digest algorithm should be re-issued by your provider with a stronger hash algorithm.
Would you be able to check that it is the correct diagnostic? If you have a PEM file, you can see mentions of the hash algorithms in the "Signature Algorithm" fields when using the following command: openssl x509 -in cert.pem -noout -text -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssl in Ubuntu. https://bugs.launchpad.net/bugs/1972939 Title: Jammy tinc incompatibile with older (e.g. Xenial) tinc nodes Status in Release Notes for Ubuntu: New Status in openssl package in Ubuntu: New Status in tinc package in Ubuntu: New Bug description: The tinc included in Jammy (1.0.36-2build1 linked with libssl3) cannot connect to tinc nodes running e.g. tinc from Xenial (1.0.26-1).
