I will likely regret this as it's a website selling digital marketing services so know your going to be extra harsh. Please keep in mind all leads for website design and development go to a local website development company who made our original website. I have recently remade our site and wanted some feedback. https://ram-digital.co.uk
That's strange views fine on all devices I have tested on including Firefox, Chrome and Edge on my laptop. My phone my desktop. List goes on. SSL certificate issues that sounds like but was there any further data? Had no issues while running SEO audits or anything listed in Google Search Console. I have multiple other people who work in the company checked the site and none have had issues. We have a good stream of visitors with good bounce rate. I find it very odd you're getting that error.
