[Solved] Argocd invalid username and password

 

After installing the Argocd in kubernetes facing issue during the login to Argocd UI in browser with error  invalid username or password

Error:-

Invalid username or password

 

Cause:-

MosCt of the places you will find that the initial password for the Argocd is the container name with argocd-server or argocd-server.namespace but by entering both of them you would still go through the same issue and it wont login. Argocd set up a one time password and you wont be able to decode the password which is in secrets manager as that password even dont work.

Error: SSL certificate problem: self signed certificate in certificate chain

 

Cause:-

If you're encountering a "self signed certificate in certificate chain" error when using Vagrant, it means that the SSL certificate used by the server you're connecting to is not trusted by your system because it is self-signed or not signed by a trusted authority. This can be a security risk, so there can be 2 cases

1. In some cases(testing) it may be acceptable to temporarily disable certificate validation for testing or development purposes.

2. you need to use a self-signed certificate for SSL/TLS connections in a production environment, you can add the certificate to the trusted certificates on your system.

Based on your use case you can implement any of the solution mentioned below
