Installing a Gateway (secondary)

Issue:

After entering Primary server address and Account name, installer takes time and displays this error message

Verify Internet connectivity, ex with a 'ping'
Verify DNS name resolution for the Primary server:
```
$ nslookup primary.eu.eophcp.com
```
Verify access and latency to connect to the ports on the Primary server
```
$ telnet primary.eu.eopchp.com 2560

etc...
```

Review Network settings
```
$ sudo nmtui
```
Verify Account name has been correctly typed and correspond to the Domain defined in HCP console for this Account
If latency is the problem, it can be due DNS or network environment, you can try to work-around this by using 'hosts' file for name resolution:
- edit /etc/hosts ( using 'vi' or 'nano' editor / or using Mobaxterm and editing the file)
- enter values like:
```
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
34.252.199.173 primary.eu.eophcp.com
34.252.199.173 acme.eu.eophcp.com
```
