ERROR#203: Network service error
Cannot connect to relay servers
Source-Connect | Version 4 | All Operating Systems
Description
When users attempt to connect to a user via Source-Connect 4, they receive the following error message:
Reason
A connection to the relay servers is not possible. This might be caused because:
- You might have multiple IPs (for example, due to virtual machines).
- There are corporate network & firewalls blocking the access.
Actions
In order to fix the error message, try the following steps:
- Make sure you have internet access by trying to go to our website http://source-elements.com/. If you do not have internet access, try
rebooting your router and computer and starting Source-Connect back up. If you are able to access our
website via web browser but still cannot log into Source-Connect, it may be a firewall issue where your
firewall is blocking traffic on port 80 TCP. Move on to the next instruction.
- Check your firewall, antivirus, VPN or IP (the IP must be correctly configured on
port forwarding). Make sure none of them are blocking port 80. This issue is usually
related to very strict networks, so if you are still unable to log in at this point, we will need more
detailed information regarding your network settings to proceed.
- Make sure that you do not have more than one active network (Wifi/Ethernet etc) in
your System/Preferences/Network settings. Ideally only one is "green" and all the others are "red." If
you need to have two active network devices at the same time, then make sure your internet connection is
set at the top (look at the bottom of the list to the settings gear to "set service order" to make sure
that is correct).
- Were there any recent network changes? Was Source-Connect previously working and
suddenly stopped after these changes? Contact your network provider.
- DNS settings can be the problem. Try adding 8.8.8.8 and 4.4.4.4 to your network's DNS settings.
You can contact the support team in order to get a document with the IPs you need to whitelist.
