Unable to switch job in Devops Engineer Field

Hi All, I need suggestion from everyone from software/cloud/devops industry. As right i in a very worst condition. After working 2 years straight as aws cloud engineer i joined a product based company which promised that the work i’ll be doing is will be related cloud, devops and automation. But since one year i haven’t got any work which was promised else they provide me work to automate onprem network devices automation that too i have to request my team to give me some work. As i am the only one in the team who knows automation and cloud related things. I try to gave some interviews but some say no because of current salary and for some of them they have very high expectations as i am 3 years experienced guy. Can anyone who have been through same situation please guide me or help as i really wanted to grow technically but i am unable to.
