Logging into router from Chrome

[Preskitt.man]

Curious thing recently started happening when I log into the router (RT-AC68U running Merlin 380.70). When I use Chrome (currently Version 70.0.xxxx), the login screen comes up normally. I enter userid and password. There's a very brief flash and I am right back to the login screen. No error message - just the flash. Can't get past it. It does work with Edge and Opera. I have cleared the cookies in Chrome - made no difference. Can't really say this began happening with Version 70 of Chrome, but it may have. So, not earth shattering, as I do have a work around, but very curious. Wondering if anyone else experience this? What you may have done.
