But the errors are all about voice.temtrampo.com.br, right? video.temtrampo.com.br doesn't even have an IP address associated with it, so I'll assume the correct hostname is voice.temtrampo.com.br indeed.
Anyway, is there a firewall blocking requests for port 80 (and 443)? Because I can ping your server, but I cannot connect to port 80 nor port 443:
osiris@erazer ~ $ ping -c 3 voice.temtrampo.com.br
PING voice.temtrampo.com.br (152.67.41.225) 56(84) bytes of data.

So the host is up using ICMP packets.. But:
osiris@erazer ~ $ telnet voice.temtrampo.com.br 80
Trying 152.67.41.225...
telnet: connect to address 152.67.41.225: No route to host
osiris@erazer ~ $
and:
osiris@erazer ~ $ telnet voice.temtrampo.com.br 443
Trying 152.67.41.225...
telnet: connect to address 152.67.41.225: No route to host
osiris@erazer ~ $
A regular traceroute (which uses UDP I believe) also fails, without any error. Using ICMP (like ping) works again, no problem:
osiris@erazer ~ $ sudo traceroute -I voice.temtrampo.com.br
traceroute to voice.temtrampo.com.br (152.67.41.225), 30 hops max, 60 byte packets

But when using TCP port 80 (or 443): it gets blocked at your server:
osiris@erazer ~ $ sudo traceroute -T -p 80 voice.temtrampo.com.br
traceroute to voice.temtrampo.com.br (152.67.41.225), 30 hops max, 60 byte packets

Looking at the traceroute for TCP port 80 it looks like it's the server itself.
Alternatively, the dns-01 challenge could be an option. However, I have NO clue what so ever how to do that using Jitsi.
