Debian GNU/Linux 10 (buster) and FreedomBox Version 19.1. (stable) downloadet from Freedombox.org, for RaspberryPi 3b+ Firefox 68.01 on manjaro Linux

Update:

After uninstall Tahoe-LAFS manually with apt via ssh (and delete the folder tahoe-lafs in /var/lib) and than reinstall Tahoe-LAFS was running but when I tried to call the page I got again:

SSL_ERROR_RX_RECORD_TOO_LONG.

I tried in Firefox via about:config to go down with: "security.tls.version.max* from 4 to 3

but no different. What i see is my domain name two times in a row!
foto1|690x425
where can I see if this is really registered in the configuration two times in a row or not?
Today i created a backup of the sd card with dd and now the service Tahoe-LAFS is not longer running.
Ifi try to start the service manually i get:
Job for tahoe-lafs.service failed because the control process exited with error code

I’m seeing the same issue when trying to start tahoe-lafs:
