Connection timed out

[ictinc]

I'm trying to build. However Maven spits out a couple of errors like these:

[INFO] Scanning for projects...
Downloading from beta-nexus: https://beta-nexus.mcc.schubergphilis.com/content/groups/public/org/springframework/boot/spring-boot-starter-parent/2.0.1.RELEASE/spring-boot-starter-parent-2.0.1.RELEASE.pom
[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[FATAL] Non-resolvable parent POM for cloud.cosmic:cosmic:6.1.12-SNAPSHOT: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.0.1.RELEASE from/to beta-nexus (https://beta-nexus.mcc.schubergphilis.com/content/groups/public): Connect to beta-nexus.mcc.schubergphilis.com:443 [beta-nexus.mcc.schubergphilis.com/85.222.237.248] failed: Connection timed out (Connection timed out) and 'parent.relativePath' points at no local POM @ line 35, column 1

I tried to connect to this host manually and this also failed. Is it correct this host is down? Any idea when, if ever, it's coming back?
Thanks in advance..
