High uric acid and protein intake

Hey docs! M24, I weigh around 85 kgs and I'm 6ft tall, so I've been hitting gym from the last month, after a gap of 1 year or so, and in order to hit my daily protein goals, I eat around 1/2 kg boiled chicken everyday via 2 meals in a day.

So, long story short, I recently had a regular Full body check up and my uric acid reading was 6.9 mg/dl (normal range being 3.5-7mg/dl), the doctor told me that it is because of high protein intake and I should be having no protein at all, so can any one of you suggest here if that's true or not, I highly doubt that's the case, based on the preliminary research I've done; and what should be my course of action on this?

Moreover, I've a slight pain in my knee joints from the past few days, is that because of high uric acid?

Any help on this would be highly appreciated. Thanks (you guys are just amazing btw)!
