"The name of the security certificate does not match" Message Appears
If a message beginning with "The name of the security certificate does not match . . ." appears when you
are accessing Web Config using SSL communication (HTTPS), the product's IP address on the CSR or
self-signed certificate does not match what you entered in the browser. Change the IP address you
entered for the Common Name setting, and obtain and import a certificate again, or change the product
name.

Model Name or IP Address Not Displayed in EpsonNet Config
If the product model name and/or IP address is not displayed in EpsonNet Config, try these solutions:
• If you selected to block, cancel, or shut down option on a Windows security or firewall screen, the IP
address and model name cannot display in EpsonNet Config. Register EpsonNet config as an
exception in your firewall or security software, or close the security software and try running EpsonNet
Config again.
• The operation may have timed out. Select Tools, select Options, select Timeout, and increase the
time option for the Communication Error setting. This may cause EpsonNet Config to run slower,
however.
