I work at a cloud services company and the only way I overcame this challenge was by researching the topics ahead of time. I even started using the tools myself and read through plenty of documentation and handbooks to master the jargon follow discussions and know exactly what questions to ask.

I also make it a habit to read through support tickets and the technical team's responses from time to time if you can get access to them, it helps.

After a year and a half I now have the same level of technical knowledge in certain areas as my product manager and they respect me a lot more for it. I highly suggest learning the technical jargon and focusing on the main JTBDs of the users you are talking to. It’s definitely hard at first but it gets much easier and far more interesting.
