I need your help. I have an app in the app store which is based on ionic and build with phonegap build. Since last week some of my users cannot login into to the app anymore. I already tried to debug on the server side but the request does not even reach the server. The weird thing is that the problem started to appear last week before that everything worked fine. It seems to occur only on some phones, but I cannot see a pattern of smartphone type or android version. I already read most of the related posts and checked the following possible reasons:
Missing CSP: I have following CSP entry in my index.html
<meta http-equiv="Content-Security-Policy" content="default-src *;img-src * data:; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">
And following entry for the whitelist plugin in the config.xml
<access origin="*" subdomains="true"/>
<allow-navigation href="http://*/*" />
<allow-navigation href="https://*/*" />
<allow-navigation href="data:*" />
I also checked the “Access-Control-Allow-Origin” and Access-Control-Allow-Headers on my node.js server
res.header("Access-Control-Allow-Origin", "*"); res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization");
The release version is working on the phones of our team but some people have problems. Did anyone of you encounter a similar problem? Or does know a starting point where to look for the problem? I would really appreciate your help, because I already tried everything I have in mind.
Best regards,
Peter
