I am consistently suffering an inability of MO to login to Nexus. I've confirmed my username / password combination by logging in & out of Nexus via Google Chrome. On the off chance it was the infamous Google Chrome SNAFU with handling external programs I tried the debugging steps shown multiple times in this topic section. I happen to be running Windows 10, and have attempted to use the 8 debugging steps for google chrome while it was set as default web browser, and also tried using internet explorer & edge as default web browser and performing steps 1 & 2. Additionally, I have used the workaround section for which I have updated the NMM version to reflect what is on the web page i.e." 0.61.23 " I did have partial success in that clicking the green download NMM button does properly instantiate a download attempt via MO. Unfortunately for me there was no success with logging in to Nexus so the download eventually fails.
