I’ve got Vikunja up and running for many months but since last update got 502 bad gateway.  
I’ve got in frontend the following error :  
2023/03/11 17:48:55 [emerg] 1#1: bind() to 0.0.0.0:80 failed (13: Permission denied)  
nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied)  
And in API :  
info: creating the new user vikunja with 1026:100  
groupmod: GID ‘100’ already exists  
Was thinking is a swag issue and tinkering around nginx but seems a Vikunja issue  
Don’t know where to start … help will be gladly appreciated

Latest version fixed the regression. I’m closing. Thanks a lot for the reactivity.
