Trying a different browser has almost always helped us when this web connection issue happens. Have seen this a lot on both the 4 and 8 series and the other day this happened to a customer exactly as you described the issue (could print just fine but could not access the web interface) on a older C203. Using Firefox resolved it.
Also, Some functionality may be unavailable while the Enhanced Security mode is activated. So check and see if Enhanced Security / Bizhub secure is enabled.
Most of the time Chrome will work absolutely fine but apparently Konica has specifically designed their Web Connection interface to be focused on compatibility with the microsoft and mozilla firefox browsers. See below:
Web Connection is a built in utility software product for management use.
By using a Web browser on your computer, you can simply confirm the status of this machine and configure various machine settings.
Although character input such as address entry and network setting is a difficult process using the touch panel, it can be carried out easily if you use the computer.
