Could Disallow: /page/ cut traffic?

Question

Search Engine Optimization

Good afternoon, this is the essence of the problem. We recently updated the site on dle and the traffic on the site slightly sank. Previously, canonical was set for pagination pages, now Disallow: /page/ is closed, could this affect the traffic reduction?

Answer 1

well, you open the webmaster and the metric and see what the problem is

Answer 2

After updating the engine, the traffic began to fall, and what exactly was the reason I'm trying to figure it out. There are no errors in the webmaster. For now, I'm sinning on a closed Disallow: /page/

Answer 3

Return canonical (the link should lead to the first page) in the pagination. This is the only correct method for optimizing this type of page.
