Yeah, the problem seems to be resolved in the current version of KIS 21. Thanks for all the people being involved in the solution. Sincerely, Pascal Schweitzer

I have submitted a case. The ticket ID is: INC000011996316

I am experiencing exactly the same. I am a scientist using jupyter lab within the Anaconda distribution for scientific coding. I was clever enought to define some exclusions in the web anti virus settings tab for localhost:8888, where I run my jupyter lab server. This solves the problems only for a few minutes. Afterwards the same error is thrown again: [W 01:35:16.516 LabApp] 403 PUT /lab/api/workspaces/lab?1602891315216 (::1): '_xsrf' argument missing from POST [W 01:35:16.516 LabApp] '_xsrf' argument missing from POST [W 01:35:16.518 LabApp] 403 PUT /lab/api/workspaces/lab?1602891315216 (::1) 585.81ms referer=http://localhost:8888/lab [W 01:35:16.979 LabApp] 403 PUT /lab/api/workspaces/lab?1602891316966 (::1): '_xsrf' argument missing from POST [W 01:35:16.983 LabApp] '_xsrf' argument missing from POST [W 01:35:16.984 LabApp] 403 PUT /lab/api/workspaces/lab?1602891316966 (::1) 13.99ms referer=http://localhost:8888/lab [W 01:35:17.108 LabApp] 403 POST /api/sessions?1602891317096 (::1): '_xsrf' argument missing from POST [W 01:35:17.108 LabApp] '_xsrf' argument missing from POST [W 01:35:17.110 LabApp] 403 POST /api/sessions?1602891317096 (::1) 3.00ms referer=http://localhost:8888/lab [W 01:35:17.112 LabApp] 403 POST /api/sessions?1602891317094 (::1): '_xsrf' argument missing from POST [W 01:35:17.114 LabApp] '_xsrf' argument missing from POST [W 01:35:17.114 LabApp] 403 POST /api/sessions?1602891317094 (::1) 7.00ms referer=http://localhost:8888/lab If I completely deactivate anti bannner, the Jupyter Lab server is working just fine. I suggest to your developers to consider this issue as urgent, since there are a lot of critical scientific tasks to be solved by Jupyter. In relation to the pandamic crysis, this may even save or destroy lifes.
