Does this section apply to you?
If you have one of the products below installed, this section applies to you:
- ESET Security Ultimate
- ESET Smart Security Premium
- ESET Internet Security
- ESET NOD32 Antivirus
- ESET Small Business Security
- ESET Safe Server
- If your router or hardware firewall causes ESET activation issues, contact your internet service provider to add the necessary Hostname, IP address and Port number to your router or firewall.
- If your router or hardware firewall causes ESET update errors (for example, "Modules update failed" or "Error downloading Update Modules"), you can use the Troubleshooting wizard to unblock applications or add exceptions. If this does not resolve the issue, undo the changes and contact your internet service provider.
- If you are a home or small office product user that is part of a school or business, contact your network administrator to add the necessary updates.
- You can provide this article to your internet service provider, network administrator or firewall provider, which includes Hostname, IP address and Port information that should be added to the firewall or router.
TCP/UDP port 53535 must be open
Communication with ESET's servers has changed as of Endpoint v8.1 and communication on UDP and TCP port 53535 must be allowed on a firewall for ESET LiveGrid®, Antispam and Web Control to work. To resolve an ESET product with a limited Direct Cloud connectivity issue, TCP/UDP port 53535 must be open.
Your ESET product communicates with resources on the internet over standard HTTP protocol on Port 80, or over HTTPS on Port 443.
To resolve your issue, the following hosts in each ESET component must be made accessible:

The IP address of the ESET repository server in China: 161.189.152.208
Some locations (such as Japan, Australia, or New Zealand) might have different IP addresses because of using CDN.
Use repositorynocdn.eset.com to connect ESET repository servers only; however, in this case, the best internet connection cannot be guaranteed.
Ensure HTTP 1.1 is enabled when accessing the repository or ESET update servers via third-party proxy. This applies to all products that have access to the ESET repository.

Telemetry
Telemetry services:
Certificate Revocation Checks (OCSP)
Some third-party applications (for example, web browsers) check the revocation status of SSL/TLS certificates via Online Certificate Status Protocol (OCSP).
- 93.184.220.29
- 72.21.91.29
- 192.16.58.8
- 117.18.237.29
- 66.225.197.197
OCSP status has to be requested over HTTP
For some certificates, to verify an OCSP status has to be requested over HTTP. Ensure that your ESET product does not block such requests to avoid problems, for example, long verification times due to timeouts.
Syslog security restrictions and limits
Additional security settings:
