Can't access PubMed webpage
Hello,
I can't access https://www.ncbi.nlm.nih.gov/pubmed/ with any browser (Safari, Chrome) in my computer iMac. I tried to clean cache, cookies, history but is still not working. I also restarted the router and the computer, but no answer. I am using macOS Big Sur 11.4 which was updated on the 29th of May 2021. I think that since then, I have this problem. ¿Can you help me please?
PD. The webpage is working properly with other computers and browsers in my workplace but is not working with my different devices (iMac, iPhone).
iMac 21.5″, macOS 11.4
