Could you please check the host file located C:\Windows\System32\drivers\etc\
Please check if anything related to Adobe is written at the bottom. If yes, then remove it and save the host file to the same location.
Then check if you able to sign in and let us know about the outcome.
do you mean the file "hosts" in that directory?
The whole content of this file is:
# Copyright (c) 1993-2009 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 18.104.22.168 rhino.acme.com # source server
# 22.214.171.124 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
So if I understand this correctly then there are no actual entries, just comments?
I tried to solve the problem by un-installing lightroom and creative cloud, then re-installing both. The problem is still there and now I have the additional problem that nothing seems to happen when I try to open my catalogue. I am starting to get really frustrated...
Try creating a new admin user account the install lightroom on it and let me know if it works.
What I have meanwhile done is re-install my whole operating system. That solved it, although it was probably not the most elegant solution.
Anyway, thank you.
Glad you got it working! Feel free to reach out to us for any future queries.
