This may be unrelated, but happened at the same time roughly 3 days ago.

I am using a ASUS NUC server X86, latest yunohost release. The trigger for not being able to bridge anymore could be the recent upgrade of synapse to 1.69.0~ynh1 . The error message in the log talks about an SSL Handshake error. This is true for all Signal contacts.

Should it be related to #59 ?

[Gredin67]

I think it's related to https://gitlab.com/signald/signald/-/issues/343
Upgrading signald to v0.23.0 should solve the issue. So upgrading the bridge should solve the issue.

[Gredin67]

possible workaround (not really tested) for those who are still under Yunohost 4 (debian 10), upgrade signald without upgrading mautrix_signal :

app=mautrix_signal
source /usr/share/yunohost/helpers
ynh_install_extra_app_dependencies --repo="https://updates.signald.org unstable main" --package="libunixsocket-java signald signaldctl" --key="https://updates.signald.org/apt-signing-key.asc"

[Gredin67]

solved by #63
