    Troubleshoot AWS Route 53 Issue 13 orё left
    VERIFIKUAR

    I have a node application running in an Ec2 container on port 443. I've added an Elastic IP to the container. When I reference the Elastic IP or IPv4 DNS in the browser, I can see my application. I added a Loadbalancer and attach it with the IP address. When I reference the load balancer in the browser, it also displays my web app as expected. This is where it gets interesting. When I add a cname I'm getting mixed results. If I'm on my wifi network the site does not appear. When I use my phone data it does appear. I'm using certificate manager, which routes all 80 traffic to 443 so I'd expect something to appear. Nothing has yet. I'm looking for a Dev Ops Engineer to trouble shoot the issue.

    Hello, I have a problem with google analytics reporting visits from the same IP addresses randomly as UK or USA. I use 50 UK IPs to connect to my website. GA reports the visits as UK one day and as USA the next day (It can also change from one hour to another). The strangest part is that when I use the UK proxies from my personal PC the visit is reported as UK on Google real time reporting (I am not located in UK). But when I use the UK proxies on a windows server hosted in US datacenter dedicated windows server, the same residential proxy IP is reported as from USA or UK randomly by GA. Some ours USA and some other hours UK.
