http://localhost:8888/ is not responding

When I launch jupyter notebook from the anaconda navigator or from the command line, then I get this error. Browser pops up this url but it does not respond: http://localhost:8888/tree?token=ce7df169cfe8da7101ad95142193289d2a3b7524db86a998

Error log from Anaconda Navigator:
