    Description

      Dear Zabbix Team,

       

      I have some server instances on AWS, using Lightsail services. Zabbix repos are not available for a while on one of the servers, they used to work before.

      This seems to be a networking issue on your end, I have no firewall blocking traffic on my side, nor in the VPC. You can see traceroute is dying on us halfway.

      My src ip is: 18.184.191.113

      I tried to telnet to port 443 from the specified host and it does not work. Random host is working. I even inserted allow filter into the firewall to avoid possible blockage, but did not help. All these are working without problem from my other hosts.

      Somehow it seems there is filtering on your end.

      Please advise.

       

      Best

       

      Pal Vig
