G+_Jason Marsh Posted October 26, 2015 Share Posted October 26, 2015 Hmmm, so it fails network setup but has address and serves web admin page... Is there vomitus on the ceiling? Link to comment Share on other sites More sharing options...
G+_Akira Yamanita Posted October 26, 2015 Share Posted October 26, 2015 I checked out the manual and it looks like either something that shouldn't have been turned on (such as IPsec, secure IPP, or 802.1X) was turned on or the certificate expired.

G+_Jason Marsh Posted October 26, 2015 Share Posted October 26, 2015 I've seen invalid certs because of system time getting reset. Can you check that the time and date on the devices are correct? This would be for both the printer and the client you're accessing the printer from. If the date is correct, I'd reset to factory defaults and go back through the hassle of reconfiguring it.

G+_Rud Dog Posted October 26, 2015 Author Share Posted October 26, 2015 Jason Marsh it only serves up the "web admin" page when I connect via WiFi other wise can't access the printer. Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted October 26, 2015 Author Share Posted October 26, 2015 Akira Yamanita Did not realize my printer used HTTPS till it failed in fact don't think it did but can't be sure only because when it is working it gets no oil. It is hard to believe they assigned any type of security to the printer is this common? I mean would they assign a cert to a printer and if so why have such a short span in time as I am sure most consumers know nothing about certs and how to work with them. A bit puzzling> Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted October 26, 2015 Author Share Posted October 26, 2015 Jason Marsh So you are of the camp there is a cert on my printer and somehow my date was corrupted and the cert time length time was beyond the expiration. Which prompts the question; are certs expiration based on a date in the future or timer in days or years? Also if the cert is the culprit does it not also apply to the Wifi connection or does it have its own cert and if so what date format does it use?

G+_Jason Marsh Posted October 26, 2015 Share Posted October 26, 2015 The cert wouldn't be generated by your printer, but if system time was way out of sync you could have cert issues. It seems something is corrupted in the config or the firmware. I saw your other post, and it appears you've reset the config. Have you tried updating the firmware? This also might sound crazy, but what happens if you use a different browser to interact with the admin pages for the printer? I've had a NAS and a print server that didn't play well with Chrome, so I used IE for them and everything was fine. Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted October 26, 2015 Author Share Posted October 26, 2015 The crazy approach is sometimes helpful but in this case using Firefox instead of chrome still got me the same warning. 192.168.1.13 uses an invalid security certificate. The certificate is not trusted because it is self-signed. The certificate is only valid for the following names: 192.168.0.2, 192.168.0.2, EPSOND400E6.local., EPSOND400E6 (Error code: sec_error_unknown_issuer) BTW on the website for drivers this Epson400E6 is shown to be good for the printer I have in case you notice the pic having a different name. Next stop firmware. Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted October 26, 2015 Author Share Posted October 26, 2015 PS Date and time check out ok on both the printer and PC. Link to comment Share on other sites More sharing options...
G+_Jason Marsh Posted October 26, 2015 Share Posted October 26, 2015 Hmmm.. Self-signed.. So maybe the printer does generate the cert. It looks like the cert may have been generated when the device was on a different subnet than where it now lives. (was 192.168.0.x, now it's 192.168.1.x) If you change the device/netbios name will that cause it to generate a new cert? The admin guide points out that javascript should be enabled in your browser in order to setup HTTPS/SSL access; is it? Link to comment Share on other sites More sharing options...

G+_Jason Marsh Posted October 26, 2015 Share Posted October 26, 2015 See "Using a Digital Certificate" on page 30 through "Updating a Self-signed Certificate" on page 34. Whatever's broke, it's right there. Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted October 26, 2015 Author Share Posted October 26, 2015 Well finally got through to Tech Support and an hour later we are good to go. Someone nailed it apparently some how some way the printer was placed in WiFi mode and this disables Wired ethernet port connection. If someone is reading this and has the same problem be aware disabling the WiFi is rather obscure. Press the wifi icon in the upper right hand corner of the display on your printer. Then select wifi/network settings From there find the setting stating disable wifi. One that was done all was well in printing land. The one thing they could not help me with was the privacy error I am still getting on my browser screen when attempting to connect to my printer. Tech Support suggested I contact google.

G+_Rud Dog Posted October 26, 2015 Author Share Posted October 26, 2015 Thanks Jason Marsh will check that out. Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted October 26, 2015 Author Share Posted October 26, 2015 Jason Marsh Now with my hardwired Ethernet connection up and working updated the self signed cert.. Not sure what that means but will do some testing and post later. Link to comment Share on other sites More sharing options...
G+_Jason Marsh Posted October 26, 2015 Share Posted October 26, 2015 Looks like I got caught chasing one rabbit while you were going after the other, but glad you got the network setup fixed. Now back to my rabbit :) ... Note that your browser will still pitch a fit about the self-signed cert. You know where the cert comes from so it's ok to trust/import the cert if the browser warning is very annoying to you. Their remark that you may want to talk to google stems from google's push to raise security alarms, warning users about untrusted certs, SHA1 certs, etc... I get that they're trying to make the 'net a better place, but the average user just doesn't get it anyways. I had to import and explicitly trust the cert for my WHS2011 box because google (and then the rest of the browsers) started pitching a fit because it's a SHA1 cert. OMG, somebody's gonna hack my network and steal my media and family photos from my homeserver. Oh noessss!!! Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted October 27, 2015 Author Share Posted October 27, 2015 Yeah not to up on the certs thing but did manage to setup a self signed cert but not sure what that does beings the original warning pic I posted at the start still comes up when I use my browser to access my printer. Maybe in the middle of the night the answer will come to me or later on in the next year. Anyhows thanks for the input enjoyed following the trail to the end well almost.

G+_Jason Marsh Posted October 27, 2015 Share Posted October 27, 2015 the cert is so that you can connect to the device over SSL. If it's not a hostile environment (same subnet as a coffee shop hotspot) or an enterprise environment I wouldn't worry about it. Link to comment Share on other sites More sharing options...
